摘　　要：为了提高TDD-LTE上行链路随机接入信道处理的高效性,提出一种基于欠采样时域分步处理的随机接入检测算法。与传统方法相比,降低了运算的复杂度,同时分步处理的调度机制提高了接入响应的实时性。实验结果表明,在不同的信道环境下,该算法都具有良好的检测性能。This paper proposed a random access detection algorithm based on under-sampling and stepping process,which had improved the efficiency of the response to random access in TDD-LTE sysytem.Compared to traditional method,the new algorithm can reduce the complexity and give the real-time characteristic.Simulation results prove that this method shows good performance in various wireless channels.
