本文分析了分布式Turbo码软译码转发（SDF）的误块率（BLER）和误比特率（BER）。联合界（UB）在衰落信道推导和仿真结果进行了比较。为了得到块衰落情况下的紧界，使用了限前平均技术。此外，我们将我们的分析扩展到时空合作框架。分析和仿真表明，所导出的界是很紧的。
In this paper, we analyze the block error rate (BLER) and bit error rate (BER) of soft decode-and-forward (SDF) using distributed Turbo codes, which is proposed recently to mitigate error propagation caused by decoding error in the relay node. Union bound (UB) in fading channels is derived and compared with simulation results. In order to get tight bounds for block fading case, limit-before-average technique is used. Furthermore, we extend our analysis to the space-time cooperation framework. The analysis and simulation show that the derived bound is very tight.
