A Set Of Orthogonal Space-time Block Codes For The High-rate Transmission With One Additional Information Bit

5080,5081,5082,5083,5084

In [1], the authors have proposed one high rate transmission
scheme for Space-Time Block Codes (STBC) without additional system
source such as power, bandwidth and time slot. To maintain the
full rank property of the coding gain matrix, we propose a set of
STBCs for 4 transmit antennas transmission to transmit one
additional information bit achieving rate-9/8. Another orthogonal
STBC code with rate-1 is proposed in this paper within the set. It
shows by computer simulation results that by employing the set of
STBCs, it achieves better bit error rate (BER) performance and
throughput than that of [1] with a valid BER improvement at the
high SNR region above 20dB.
