摘要
针对3GPP最新发布的LTE-A Relaease10标准,通过对两种软解调算法的仿真比较,权衡时间复杂度和算法性能,选择了一种最适合TD-LTE无线综合测试仪表的软解调算法,并通过TMS32064xDSP实现。提出了一些具体的软件优化策略和技巧,对max-log-map算法进行了大量化简。基于集成化开发环境CCS3.3,编程实现LTE-A软解调算法,运行结果验证了max-log-map算法的可行性、高效性。
Based on the recently released LTE-A R10 standard by 3GPP, this paper researched two soft-metric demodulation algorithms which were used commonly. Balancing the complexity of the time against performance of algorithms l it chose the most suitable internal interleaver algorithm for the TD-LTE wireless integrated test instrument, and realized the algorithm in the TMS32064xDSP. It presented a number of specific strategies and techniques for software optimization and greatly simplified the algorithm of max-log-map. The operation results of the soft-metric demodulation program in CCS3.3 verify that the algorithm of max-log-map is feasible and effective.
