Patent number: 8489041Abstract: An improved communication system and method employing an actively controlled antenna array architecture is disclosed. The array contains a plurality of driven radiating elements that are spatially arranged having a pair of radiating elements fed with an RF signal predistorted so as to provide a controlled variation of the antenna array's elevation radiation pattern. High power amplifier (PA) efficiency is maintained by adaptive predistortion, coupled to each high power PA, while providing beam tilt and side lobe control.Type: GrantFiled: June 7, 2010Date of Patent: July 16, 2013Inventors: Anthony Teillet, Scott Carichner, Alexander Rabinovich

Patent number: 8073385Abstract: An adaptive echo cancellation system and method employing an algorithm suitable for a digital repeater with sub-band filtering is disclosed. Cross- and auto-correlation measurements used to estimate the residual coupling are computed from normalized cross and power spectrums which avoid the problems associated with narrow bandwidth signal components. The normalized cross- and power spectra are additionally masked in frequency to reduce the influence of interfering spectral components outside of the passband of the sub-band filter. Regularization of the iterative estimation process is applied to maintain stability and compensate for the bandwidth reduction associated with the sub-band filter and the spectral mask.Type: GrantFiled: May 19, 2009Date of Patent: December 6, 2011Assignee: Powerwave Technologies, Inc.Inventors: Richard Neil Braithwaite, Scott Carichner, Mark Cope

Patent number: 8068783Abstract: A wireless repeater includes an input antenna for receiving an input signal, an output antenna for outputting an amplified signal, and an amplifier for amplifying the received input signal and providing the output amplified signal to the output antenna. Radiated coupling between the input and output antennas causes echoes to be transmitted by the repeater. A filter is used for applying a weighting function to a power spectrum of a measured signal in the wireless repeater thereby obtaining a weighted power spectrum of the measured signal. An internal feedback path is employed for adaptively canceling the echo by implementing an adaptive algorithm based on a autocorrelation of the input signal employing the weighted power spectrum of the measured signal.Type: GrantFiled: January 22, 2008Date of Patent: November 29, 2011Assignee: Powerwave Technologies, Inc.Inventors: Richard Neil Braithwaite, Scott Carichner

Patent number: 7769103Abstract: A predistortion linearized amplifier system that uses analog polynomial based predistortion is disclosed. An analog polynomial function generator receives polynomial parameter updates from a polynomial parameter generator. The polynomial parameter generator uses a combination of analog and digital signal processing to create the parameter updates. This processing is performed on input signal amplitude, detected using analog circuits, and RF coupled samples of the input signal, and the output signal. By using a combination of analog and digital signal processing means, digital processing can be performed at sub-Nyquist rates, significantly reducing the cost of digital circuits. Also, since the predistortion modulation signal is created with an analog function generator, time correlating delay is minimized reducing circuit costs.Type: GrantFiled: September 13, 2006Date of Patent: August 3, 2010Assignee: Powerwave Technologies, Inc.Inventors: Scott Carichner, Richard Neil Braithwaite, Nikolai Maslennikov, Matthew J.

Publication number: 20080181182Abstract: An improved digital radio head system and method for wireless communications is disclosed that simplifies the timing and synchronization between the access network, base station, and radio head. A satellite derived timing source is obtained at one or more of the remote radio heads where it is convenient to obtain and use the timing reference. The reference is transmitted back to the base station, if necessary, to synchronize the two. This is further synchronized at a lower accuracy through the access network.Type: ApplicationFiled: January 10, 2008Publication date: July 31, 2008Inventors: Scott Carichner, Anthony Demarco

Patent number: 7366252Abstract: A system for linearizing RF amplifiers employing baseband predistortion techniques provides additive or multiplicative predistortion of the quadrature (I/Q) input signal. The predistorter uses a discrete-time polynomial kernel to model the inverse transfer characteristic of the amplifier, providing separate and simultaneous compensation for nonlinear static distortion, linear dynamic distortion and nonlinear dynamic effects including reactive electrical memory effects. A predistortion controller monitors and compares the amplifier output with the quadrature input signal to compute estimates of the residual output distortion of the amplifier. Output distortion estimates are used to adaptively compute the predistorter parameter values in response to changes in the amplifier's operating conditions. The computed values are used in the predistorter.Type: GrantFiled: January 14, 2005Date of Patent: April 29, 2008Assignee: Powerwave Technologies, Inc.Inventors: Armando Cova, Scott Carichner
