A 4x2 STBC adaptive transmission method using angle feedback information and a corresponding system

摘要

Aspects of a method and system for a 4x2 SFBC/STBC system with 2 spatial streams using angle feedback are presented. Aspects of the system include a 4x2 SFBC/STBC communication diversity system with 2 distinct spatial streams using angle feedback. A receiving station may concurrently receive signals. A channel estimate matrix may be computed based on the received signals. A rotation angle value may be computed based on the channel estimate matrix. The receiving station may transmit the computed rotation angle via feedback information to a transmitting station. The transmitting station may utilize the received feedback information to generate a plurality of 4 distinct transmit chain signals based on data symbols received via a plurality of 2 spatial streams. Each of the distinct transmit chain signals may comprise a plurality of codewords. The transmitting station may concurrently transmit the plurality of transmit chain signals via the plurality of transmitting antennas.
