摘要 新一代长期演进增强(long term evolution advanced,简称LTE-A)系统主同步信号(primary synchronization signal,简称PSS)检测中,存在几种重要的主同步信号检测算法,如直接相关(correlation,简称C)、差分相关(differential correlation,简称DC)、部分相关(partial correlation,简称PC)和镜像相关(mirror correlation,简称MC)算法.该文就这4种方案对低信噪比的检测准确度、抗载波频偏(carrier frequency offset,简称CFO)及抗多径衰落能力进行全面的分析和评估.仿真结果表明,不同环境下4种算法的性能有差异.此结果能为实际应用提供重要的参考依据. In detection of Primary Synchronization Signal （PSS） in long term evolution advanced （LTE A）systems,there exist a few important PSS detection methods,which include correlation （C）,differential correlation （DC）,partial correlation （PC） and mirror correlation（MC） algorithms.This paper made a comprehensive analysis and evaluation of the detection accuracy of low signal to noise ratio,resistance to the carrier frequency offset and anti multipath fading capability using these four methods.Analysis and simulation results showed that the performances of four methods under different environments were various.This result provided significant reference for practical applications.
