TD-LTE系统Turbo速率匹配算法及DSP实现

摘要

速率匹配是基带信号处理的重要组成部分,在深入研究3GPP协议中Turbo编码速率匹配算法的基础上,基于TD-LTE无线综合测试系统,提出了一种可用DSP实现的快速实现方案.该方案简化了实现过程,有效减小了Turbo编码速率匹配的处理延时.%Rate matching is one of the most important parts in Base-band signal processing. Based on intensive research of Turbo rate matching algorithm of 3GPP protocol and the LTE(Long Term Evolution) wireless test system, a fast rate matching implementation scheme with DSP chip is proposed in this paper. The fast scheme simplifies the whole process and reduces the processing delay of Turbo rate matching.
