Patent number: 10484055Abstract: A rate-adaptive method of communicating over a multipath wireless communication system uses multiple links such that each end of a link uses multiple transmit and receive antennas. A number of independent streams that are to be transmitted for each link is determined based on an overall system performance measure. In addition, the system may also jointly determine the best modulation, coding, power control, and frequency assignment for each link, based on an overall system performance measure. In OFDM systems, the number of independent streams, as well as the modulation, coding, and power control, may be determined on a tone-by-tone basis based on an overall system performance measure.Type: GrantFiled: August 27, 2018Date of Patent: November 19, 2019Assignee: SONY CORPORATIONInventors: Hui Luo, Nelson Ray Sollenberger, Jack Harriman Winters

Patent number: 10020864Abstract: Aspects of the subject disclosure may include, for example, a device, process or software that determines an operation between a number of pairs of antennas of a set of antennas. A pair of antennas of the number of pairs of antennas is determined based on the operation. One antenna of the pair of antennas is eliminated from the set of antennas, which results in a reduced number of antennas remaining in the set of antennas. Each of the determining of the operation, the determining of the pair of antennas of the reduced number of antennas and the eliminating of the one antenna of the pair of antennas is repeated in response to the reduced number of antennas being greater than a predetermined number of antennas. Other embodiments are disclosed.Type: GrantFiled: May 11, 2016Date of Patent: July 10, 2018Assignee: AT&T Intellectual Property II, L.P.Inventors: Jack Harriman Winters, Yang-Seok Choi, Byoung-Jo J.

Patent number: 9426009Abstract: A MIMO OFDM system includes a plurality of space-time encoders for encoding respective data blocks with independent space-time codes. The transformed data block signals are transmitted by a plurality of transmit antennas and received by a plurality of receive antennas. The received data is pre-whitened prior to maximum likelihood detection. In one embodiment, successive interference cancellation can be sued to improve system performance. Channel parameter estimation can be enhanced by weighting the channel impulse response estimates based upon a deviation from average.Type: GrantFiled: November 15, 2011Date of Patent: August 23, 2016Assignee: AT&T Intellectual Property II, L.P.Inventors: Ye Li, Nelson Ray Sollenberger, Jack Harriman Winters

Patent number: 9059764Abstract: A method of performing receive antenna selection is presented. The method executes a determination operation for a set of receive antennas, determines a maximum result of the determination operation for two of the antennas, eliminates one of the two antennas from the set of antennas, and repeats the determination and elimination process until only a predetermined number of antennas remain in the set. The signals from these remaining antennas are then processed. The present invention reduces receiver complexity and cost.Type: GrantFiled: April 14, 2014Date of Patent: June 16, 2015Assignee: AT&T INTELLECTUAL PROPERTY II, LPInventors: Jack Harriman Winters, Yang-Seok Choi, Byoung-Jo J.
