Abstract
In this paper, a full-rate complex orthogonal space-time block (STB) coding scheme for multiple antennas in time division duplex (TDD) mode is proposed. Meanwhile, we employ turbo code as channel coding to improve the performance of proposed STB code further by utilizing its soft decision information from multiple iterations decoding, random interleaver and good ability to combat the burst error of fading channel. Compared with full-diversity multiple antennas STB code schemes, the proposed code scheme can implement full rate, partial diversity and a smaller complexity. On the condition of same system throughput and concatenation of turbo code, the code has lower bit error rate (BER) than those low-rate and full-diversity codes.
