摘　　要：基于提高LTE小基站与UE随机接入速率的目的,论文提出了基于DSP芯片BSC9132的PRACH检测的优化实现,利用CIC降采样减少计算量、优化PDP计算和峰值检测算法提高计算速率,结合基带板与UE进行实际随机接入实验,得到随机接入时间缩短了近30%。此方法大大降低了LTE小基站随机接入速率,使得基站与UE的通信连接更加迅速,基站的性能更加稳定可靠。Based on the purpose of improving the random access rate of LTE small base station and UE,this paper proposes the optimization of PRACH signal detection carried out on BSC9132 DSP chip,for using CIC down sampling,reduction of PDP calculation and improving of peak detection algorithm.Combined with the baseband board and the UE for the actual random access experiment,the PRACH detection time is shortened by nearly 30%. This method is fast and stable,easy to implement. It provides an efficient solution for the implementation of PRACH detection,with some commonality.
