| 摘 要： | 在传统Turbo码Log-MAP译码算法的基础上,借鉴已有的简化算法,提出了一种改进的Log-MAP译码算法。仿真结果表明,新的算法在大大降低译码复杂度的同时较好地保持了译码性能,使其非常接近Log-MAP算法的译码性能;同时也非常有利于硬件实现。

| Abstract: | Based on the conventional Log-MAP algorithm for Turbo-codes decoding and the existing algorithm for simplifying Log-MAP,an improved algorithm is presented in this paper.Simulation results show that the proposed algorithm has performance very close to the Log-MAP algorithm for Turbo-codes decoding and can decrease the decoding complexity greatly at the same time.In addition,realization of the new algorithm by hardware is very easy. |
