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. -
