Abstract

Targeting at the demodulation of asymmetric Paired Carry Multiple Access (PCMA) signal mixed by primary and secondary signal, this paper has studied the implementation framework of demodulation. First the frequency offset and phase of QPSK modulated PCMA signal are precisely locked by phase lock loop. Meanwhile, the delay and amplitude of primary signal are respectively estimated by conjugate correlation method and quartic method. After four parameters are obtained, the interference signal is reconstructed to obtain the secondary signal after canceling the mixed signal. And the error rates under different error conditions are deduced and simulated. The impacts of each parameter error on the performance of demodulation are obtained through a comparative analysis
