Phase-shift keyed PSK signal modulation methods are coming into increasing use in modem communications. This thesis describes the implementation of three methods of computing the cyclic spectrum to determine the presence of PSK signals. The Strip Spectral Correlation Algorithm SSCA and the Fast Fourier Transform FFT Accumulation Method FAM both estimate the cyclic spectral plane. The Sub-FFT Accumulation Method SUBFAM program computes the Spectral Correlation Function SCF for a set of possible spectral frequencies for a single cycle frequency. The results of algorithm performance are presented along with a discussion of promising areas for performance enhancement and automation of signal detection and classification.
