摘要：
In this article, we present a new scheme which combines Turbo codes with transmitting diversity technique to improve the reliability of wireless communication over fading channels. We present the concatenation of 15/13, rate 1/3 Turbo code as outer code and a simple two-branch space-time block code as inner code for transmitting diversity. A suitable iterative decoding scheme based on MAP decision rule is designed. And the decoding complexity is mainly determined by the trellis complexity of the outer code. Simulation shows that additional 1.6dB gains can be obtained at a bit-error rate of 10(-5) and a frame error rate of 10(-4),for throughputs 2/3 bits/s/Hz over exponentially-correlated flat Rayleigh fading channel. It is shown that the scheme can be easily used in the 3G system with little change of equipment.
