Space time block codes for semi-orthogonal multi-access based WLAN systems

Abstract

The disclosed systems, structures, and methods are directed to a wireless local area network (WLAN) transmission architecture and transmitting methodology that combines space-time block code (STBC) encoding techniques with semi-orthogonal multiple access (SOMA) schemes to improve throughput rate performance for lower signal strength data. The transmission architecture and method includes a data processing module that is configured to digitally process and format data produced by two wireless stations. A SOMA constellation quadrature encoding module operates to apply quadrature-based modulation to the processed data and map the data to a modulation constellation based on data signal strength and data bit reliability. An STBC encoding module is configured to block encode the SOMA modulated data with orthogonal codes to produce STBC-based SOMA-symbol data having time and space diversity properties that improve throughput performance at lower signal strength levels.
