摘要

针对协作通信系统，提出一种基于门限的译码算法。在分析等效干扰噪声概率分布的基础上，给出门限的设置方法，理论分析了所提算法的运算复杂度；在设置不同门限值的条件下，仿真分析了所提算法的误码性能和对应的运算复杂度，并与已有算法进行比较。在此基础上给出一种动态门限设置策略，并将其应用于所提算法。仿真结果表明，基于动态门限设置的译码算法能够减少信噪比的译码资源消耗，获得高信噪比的理想性能。

Abstract

Aiming at the cooperative communication systems

a threshold-based decoding algorithm was proposed. A method for threshold-settings was given based on the analysis of the probability distribution of equivalent noise. The operation complexity of the proposed algorithm was analyzed theoretically. Both the error rate performance and the operation complexity were then simulated

and compared with existing algorithms. Furthermore

a strategy of dynamic threshold-settings

which was given on the basis of the analyses and simulations above

was applied to the proposed algorithm. The simulation results show that the proposed algorithm based on the dynamic threshold-settings is able to alleviate the cost of decoding resources in low SNR and get the optimal error rate performance in high SNR.
