Abstract
A new class of full-diversity space-time block codes (STBC) called semi-orthogonal algebraic space-time block codes (SAST codes) with rate one symbol per channel use is proposed. The SAST codeword matrix has a generalized Alamouti code structure where the transmitted symbols are replaced by circulant matrices. Properties of rate-one linear threaded algebraic space-time (LTAST) codes are exploited to construct SAST codes with maximal coding gain. SAST codes attain nearly 100% of the Shannon capacity of open-loop multiple-input single-output (MISO) channels. Our theoretical analysis and simulation results show that SAST codes gain several dB over LTAST codes and also outperform other STBC
