AbstractAlamouti 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). |
