Patent number: 9337946Abstract: Exemplary embodiments are related to a dual-mode controller. A device may include a controller configured to convey a signal to a low-noise block (LNB) via a transmission line and circuitry configured to sense at least one parameter of the transmission line.

Patent number: 8983495Abstract: An apparatus, method and system for geographical tracking entry and/or exiting of an asset into and/or out of a defined geographical boundary and reporting the same. Entry and exit tests compare position fixes with various thresholds and parameters to determine if the asset has entered or exited the geographical boundary. Tests are sequenced such that tests having lower levels of complexity (lower order) are performed before tests having higher levels of complexity (higher order). In this way, most position fixes are processed using computations having a lower order of mathematical complexity than conventionally implemented.Type: GrantFiled: February 25, 2013Date of Patent: March 17, 2015Assignee: QUALCOMM IncorporatedInventors: Alecsander P. Eitan, Arik S. Mimran, Russell G. Sanders

Patent number: 8942321Abstract: Methods and devices for receiving wireless signals employ compressed sensing-based estimation techniques to receive single-carrier transmissions, exploiting the common sparseness of the wireless channel, enabling signal reception in the presence of significant Delay and Doppler spreads. When implemented for an ATSC or ATSC-M/H mobile TV standard signal, the compressed sensing channel estimation algorithm enables data reception in Delay and Doppler spread conditions beyond the capabilities of conventional channel estimation methods.Type: GrantFiled: September 22, 2010Date of Patent: January 27, 2015Assignee: QUALCOMM IncorporatedInventors: Ori Shental, Alecsander P.

Patent number: 8699641Abstract: Embodiment methods and apparatus enable ATSC receiver devices to receive and process ATSC-M/H training sequences in order to improve the reception and decoding of an ATSC service. A processor within the ATSC receiver device may be configured to receive training sequences 1 and 2 of the ATSC-M/H signal. In an embodiment, the ATSC-M/H training sequence 2 may be received by correlating symbols of the two halves of the training sequence 2. If the result of correlating the symbols is greater than or equal to a threshold, the ATSC-M/H training sequence 2 may be received by the ATSC receiver and a counter for the training sequence 1 may start. The ATSC receiver may correlate two consecutive training sequences 1 to perform fine residual frequency error estimation.Type: GrantFiled: June 10, 2010Date of Patent: April 15, 2014Assignee: QUALCOMM IncorporatedInventors: Alecsander P. Eitan, Ori Shental

Patent number: 8514761Abstract: Methods and apparatus enable ATSC-M/H mobile devices to conserve power by entering a high power state at a slot reception start time that is after the start of an ATSC M/H slot and entering a low power state at a slot reception stop time before the end of the ATSC M/H slot. Data lost due to the device being in a low power state during the time between the start time of the ATSC M/H slot and the activation time and during the time between the deactivation time and the end of the ATSC M/H slot are recovered using error correction processing. The slot receive and slot reception stop times may be based on the received signal quality. The receiver circuitry may also be deactivated when the entire payload has been received and skip reception of remaining slots.Type: GrantFiled: September 21, 2010Date of Patent: August 20, 2013Assignee: QUALCOMM IncorporatedInventors: Yuval Carmel, Alecsander P.

Patent number: 8467465Abstract: Channel estimation for a wireless Orthogonal Frequency Division Multiplexed (OFDM) link having pilots on at least some carriers in at least some symbols may be implemented by performing first and second channel estimation processes. The first channel estimation process uses only frequency domain interpolation of the pilots to obtain a first candidate channel estimate for the OFDM link, and the second channel estimation process uses both time domain interpolation and frequency domain interpolation of the pilots to obtain a second candidate channel estimate for the OFDM link. One of the first and second candidate channel estimates is selected for processing a communication received via the OFDM link.Type: GrantFiled: August 3, 2010Date of Patent: June 18, 2013Assignee: Qualcomm IncorporatedInventors: Alecsander P.

Patent number: 8391904Abstract: Mechanisms for optimizing the selection of a new legal channel during regulatory domain changes and improving the user experience during changes in the underlying physical link having wide applicability to many wireless communications links are disclosed. Applications comprise cellular networks, WLANs, WPANs. Wireless USB, high speed channels for Bluetooth and other uses of WiMedia as well as a wide range of radio technologies that use a number of time and/or frequency-domain separation techniques to create multiple channels in a given portion of the RF spectrum where there is no global agreement on the use of the RF spectrum. Differences could pertain to permitted frequency ranges, permitted power levels, requirements to detect and/or avoid other radio technologies, indoor/outdoor use requirements, and many others.Type: GrantFiled: May 4, 2010Date of Patent: March 5, 2013Assignee: QUALCOMM IncorporatedInventors: John Hillan, Alecsander P.

Patent number: 8295307Abstract: System and method for transmitting data to a remote communication device to achieve desirable transmit data block size and data rate based on measurements of the communication link quality to the remote device. The method entails selecting an initial transmit data rate and power based on an initial measurement of the link quality, and a default size for the transmit data block. The data block is then transmitted to the remote, and an acknowledgement (ACK) message is received from the remote. If the ACK message indicates that the data block was properly received, the size for the next data block to be transmitted is increased. Otherwise, the size for the next data block may be decreased or remain the same. Additionally, the transmit data rate may be increased if the remote properly receives a defined number of consecutive data blocks, or decreased if the remote does not receive a defined number of consecutive data blocks.Type: GrantFiled: May 7, 2009Date of Patent: October 23, 2012Assignee: QUALCOMM IncorporatedInventor: Alecsander P.
