Cyclic Statistic Based Blind Parameter Estimation of BPSK and QPSK Signals

A cyclic autocorrelation based statistic is employed for the blind parameter estimation within the framework of the cyclostationary theory. The parameter estimation of two kinds of typical PSK modulated signals, BPSK and QPSK ones, are analyzed with emphasis in this paper. Simulation results demonstrate the effectiveness of the cyclic statistic based parameter estimation method
