Cyclic spectral analysis of phase-incoherent FSK signal by matrix-based stochastic method

Based on the Markov chain signal representation, a new matrix-based stochastic method for the cyclic spectral analysis of phase-incoherent FSK signals is presented. An exact analytical expression for their spectral correlation density function is derived applying the proposed simple and straightforward method. Some computed and graphical results of the spectral correlation characterization of these signals, based on the proposed method, are given as well.
