CA 2008595

A coherent PSK demodulator includes a frequency multiplier for multiplying the frequency of an incoming M-ary PSK signal by a factor M to extract a carrier component of the PSK signal. An adaptive line enhancer is connected to the frequency multiplier for emphasizing the line spectrum of the extracted carrier component. A frequency divider is connected to the output of the enhancer to divide its frequency by a factor M and applies its output to a product demodulator as a local carrier for demodulating the incoming M-ary PSK signal. In a preferred embodiment, a synchronizer is connected between the output of the adaptive line enhancer and the frequency divider. Alternatively, a closed-loop phase error canceller is connected to the output of the product demodulator.
