Full code rate complex orthogonal STBCS for multiple transmit antennas

摘要

Alamouti is Pioneer of Complex Orthogonal STBCS for two transmit branch diversity with code rate one. Then Tarkoh found for three and four transmit antennas with code rate 3/4 . Jafarkhni proposed for non orthogonal STBCS four transmit, eight transmit antennas with code rate one and 3/4. Weifen Su and Xian-Gen Xia Investigated matrices undertaking code rate of 7/11 and 3/5 for 5 and 6 transmit antennas. Previously 5,6,7 and 8 transmit antennas matrices of code rate with 2/3,2/3,5/8, and 5/8 proposed. This paper intends new matrices for 5,6,7 and 8 transmit antennas with full code rate(high bandwidth efficiency).
