| Abstract: | This paper introduces the conception of cyclostationary and gives BFSK signal model.Then,the expressions of cycliccorrelation and cyclic spectrum of BFSK are deduced and the BFSK cyclostationary property is analyzed.Finally,the computer simulations are given.The results are shown that the BFSK signal has cyclostationary property which is a cyclostationary signal and the cyclic spectrum has high cyclicfrequency resolution. |
