【摘要】A kind of full rate space time codes based on linear detection
with optimal transmission performance (LO-STBC) is proposed to deal
with the high complexity of maximum likelihood detection in traditional
space-time coding. The LO-STBC is designed by linear combination of
data symbols and the dispersion matrices chosen by given rule; then
the symbols in a STBC matrix are simultaneously transmitted by the
multiple transmit antennas; and the data are linearly detected at the
receivers by using the equivalent channel. Compared with the
traditional STBC, LO-STBC has the optimal transmission performance
with linear detection, can get the most obvious diversity gain using
channel coding, and can greatly reduce the computation complexity
during the application of adaptive transmission. The simulation results
and comparisons with the traditional STBC show that without channel
coding, the performance of LO-STBC approaches the theoretical
performance, and the performance advantage is about 0. 5 dB; and that
with channel coding, LO-STBC obtains higher diversity gain.%针对传统空
