PERFORMANCE ANALYSIS OF QUADRATURE CORRELATION DETECTION ALGORITHM FOR DS-SS SIGNALS
-
摘要: 本文給出了直接序列擴頻信號正交分路周期相關檢測算法的性能分析.該算法不僅對BPSK擴頻調制信號檢測效果明顯,而且對QPSK擴頻調制也是有效的.計算機的模擬結果與本文的分析是一致的.該檢測結構在信噪比SNR=-15dB時仍然呈現(xiàn)良好的檢測性能.

Abstract: The performance analysis of quadrature correlation detection algorithm for DS-SS signal is presented. The algorithm can detect effectively both BPSK and QPSK spread spectrum signals. The analytical results are confirmed by computer simulation. The simulation results show that the algorithm can detect DS-SS signals with the input SNR of -15dB. -
