The aim of this paper is to give an approach to test the equality among spectral densities of several independent almost periodically correlated (cyclostationary) processes. This approach is based on the limiting distribution for the periodogram and the discrete Fourier transform. The simulation results indicate that the approach well acts. Keyphrases: Almost cyclostationary processes, Almost periodically correlated processes, spectral density
