Abstract: In this paper, the mathematical model of binary frequency shift keying (BFSK) signal is given, the mathematical expressions of cyclic autocorrelation function and cyclic spectral density function of BFSK signal are derived, and the cyclic stationary characteristics are analyzed and proved. Finally, the Matlab simulation experiment is given. The simulation results show that BFSK signal has the characteristics of cyclic stationary and belongs to cyclic stationary signal.

Keywords: BFSK signal; cyclic spectrum; cyclostationary signal; cyclic autocorrelation function; numerical simulation
