Publication number: 20110270590Abstract: Compressed sensing is used to determine a model of a nonlinear system. In one example, L1-norm minimization is used to fit a generic model function to a set of samples thereby obtaining a fitted model. Convex optimization can be used to determine model coefficients that minimize the L1-norm. In one application, the fitted model is used to calibrate a predistorter. In another application, the fitted model function is used to predict future actions of the system. The generic model is made of up of constituent functions that may or may not be orthogonal to one another. In one example, an initial model function of non-orthogonal constituent functions is orthogonalized to generate a generic model function of constituent orthogonal functions. Although the number of samples to which the generic model is fitted can be less than the number of model coefficients, the fitted model nevertheless accurately models system nonlinearities.Type: ApplicationFiled: May 7, 2010Publication date: November 3, 2011Applicant: QUALCOMM INCORPORATEDInventors: Vladimir Aparin, Robert P.

Publication number: 20110070927Abstract: Techniques for designing a communications unit including a signal separation module for energy harvesting. In an exemplary aspect, the signal separation module includes first and second quadrature hybrids coupled by band-pass filters (BPF's). Incoming signals within the pass-band of the BPF's are directed through the quadrature hybrids and through the BPF's, and emerge as a desired pass-band signal to be processed by an RX processing module. Incoming signals lying outside the pass-band of the BPF's are reflected from the BPF's back to the first quadrature hybrid, and output as a non-pass-band signal to be processed by an energy harvesting module. In a further exemplary aspect, the signal separation module resides in a detachable module coupleable to a wireless communications device, and a signal transmitted by the wireless communications device is coupled to the signal separation module for energy harvesting.Type: ApplicationFiled: September 22, 2009Publication date: March 24, 2011Applicant: QUALCOMM INCORPORATEDInventor: Robert P.

Patent number: 7013120Abstract: Methods and apparatus for implementing image rejection in radio receivers or transmitters includes a Weaver image reject mixer modified so that only one local oscillator is used for the highest mixing frequency, and subsequent lower frequency mixing signals fed to the mixers are derived from digital frequency divider networks which produce both in-phase and quadrature versions of their pre-determined output frequencies. By using frequency dividers to generate these subsequent lower frequency signals, the intermediate frequencies walk; and when these frequency dividers are set to divide by multiples of two, generating quadrature signals becomes straightforward.Type: GrantFiled: January 8, 2002Date of Patent: March 14, 2006Assignee: Intel CorporationInventor: Robert P.

Patent number: 6993295Abstract: Methods and apparatus, in accordance with the present invention, use at least two phase-locked loop based frequency synthesizers to provide a synthesized frequency output having a step size of X, where X is less than the step size of any of the at least two phase-locked loop based oscillators. By combining a first signal having a first frequency, with the output of a first frequency synthesizer having a first frequency step size, NX, to produce an intermediate signal which is in turn combined with the output a second frequency synthesizer having a second frequency step size, MX, an output signal is produced. M and N are related such that i times M=N±1, and i, M and N are integers. By varying the output frequency of the first and second frequency synthesizers, the frequency of the output signal is changed by steps of X, where X is less than the step size of either the first or second frequency synthesizers.Type: GrantFiled: January 8, 2002Date of Patent: January 31, 2006Assignee: Intel CorporationInventor: Robert P.

Patent number: 6745018Abstract: An active cancellation device receives a model of a first signal from a local wireless transmitter. The first signal causes a coupled signal that interferes in a second signal received by a local wireless receiver from a remote wireless transmitter. The active cancellation device generates a cancellation signal based on the model of the first signal, and provides the cancellation signal to the local wireless receiver. At the local wireless receiver, the cancellation signal combines with the coupled signal and the second signal. The cancellation signal reduces the interference in the second signal caused by the coupled signal.Type: GrantFiled: September 29, 2000Date of Patent: June 1, 2004Assignee: Intel CorporationInventors: Ephraim Zehavi, Robert P.

Patent number: 5861844Abstract: A system and method for using a sectored antenna arrangement within a cellular base station to provide redundant coverage within the surrounding cell is disclosed herein. An antenna feed network connects elements of the sectored antenna arrangement to a set of communication transceivers, wherein the feed network includes a combiner array for combining selected ones of the antenna beams upon failure of one of the communication transceivers. A switch network serves to provide the resultant combined beam to an operative one of the communication transceivers.Alternately, the sectored antenna arrangement includes an antenna array having a plurality of switchable antenna elements, each connected to one of the communication transceivers. The switchable antenna elements project a set of variable-width antenna beams over the plurality of cell sectors.Type: GrantFiled: November 29, 1994Date of Patent: January 19, 1999Assignee: QUALCOMM IncorporatedInventors: Robert P.

Patent number: 5844985Abstract: A portable phone unit for use in satellite communication systems has a vertically correcting antenna module pivotally secured to the handset for free rotation about a pivot axis. The module contains a mechanism, such as a gravitational counterweight for urging the module to pivot into a predetermined vertical orientation regardless of the handset orientation. An antenna projects from the module in a direction which is vertically upright when the module is in its predetermined vertical orientation. A mast mounted antenna module can also be used to take advantage of dissimilar antenna segment weights for multiple frequency antennas. As the handset is moved into an angular orientation, the module pivots under the weight of the counterweight, or a portion of the antenna itself, until the antenna is oriented vertically.Type: GrantFiled: September 22, 1995Date of Patent: December 1, 1998Assignee: Qualcomm IncorporatedInventors: Eric C.

Patent number: 5835847Abstract: A system and method for controlling the strength of a shared resource signal transmitted by the satellite transponder in a satellite communications system. The satellite communications system includes a gateway for transmitting communications signals including a shared resource signal, a satellite transponder for relaying the signals to at least one subscriber unit (for example, a phone), and at least one subscriber unit for receiving the signals. The method includes the steps of receiving the shared resource signal, at each subscriber unit, via the satellite transponder; measuring, at each subscriber unit, a signal strength for the received shared resource signal; sending the signal strengths to the gateway; and adjusting the power of the shared resource signal transmitted by the satellite transponder based on the signal strengths.Type: GrantFiled: April 2, 1996Date of Patent: November 10, 1998Assignee: Qualcomm IncorporatedInventors: Robert P.

Patent number: 5757239Abstract: A frequency synthesizer which uses a direct digital synthesizer (DDS) to generate a highly accurate periodic signal of a frequency selected from a plurality of reference frequencies. The DDS output signal is bandpass filtered utilizing a clean-up phase lock loop (PLL) to produce a spectrally pure reference signal and promote overall fast settling time. A second or primary phase lock loop, having a much faster settling time than the first PLL, adjusts the frequency of the reference signal generated by the clean-up PLL. In one embodiment, the DDS frequency synthesizer has a digital to analog (DAC) converter coupled to the clean-up PLL. Another embodiment uses a modified DDS (without a DAC or lookup table) and feeds the most significant bit (MSB) or overflow bit from the DAC accumulator into the "clean-up" PLL. In both embodiments, the resulting synthesizer has high spectral purity, fine frequency resolution and a fast settling time.Type: GrantFiled: January 8, 1997Date of Patent: May 26, 1998Assignee: Qualcomm IncorporatedInventor: Robert P.
