摘要
详细分析了下一代无线局域网IEEE802.11ac中LCPC码的编码过程。研究了BP译码算法、Log-BP算法与MS译码算法,同时研究了改进的MS算法。搭建IEEE802.11ac系统MATLAB测试链路,经过蒙特卡洛仿真进行误码率统计,从性能和复杂度方面进行权衡,改进的MS算法更适合ASIC实现。
LCPC code encoding process is analysised in the next generation wireless LAN based on IEEE802.11ac.BP decoding algorithm,Log-BP algorithm and MS decoding algorithm is Researched.At the same time,the improved MS algorithm is Researched too.MATLAB test link of IEEE802.11ac system is tested,through the Monte Carlo simulation of bit error rate statistics,from the performance and complexity of balance,the improved MS algorithm is more suitable for ASIC implementation.
