Studies show that there are Three types of transmitter detection techniques in spectrum sensing in a cognitive radio system these include: matched filter, energy detection and cyclostationary featured detection technique.... this matlab code is for t

不同信号的循环谱（AM,BPSK,BFSK,DME等）可以直接使用，来分析信号的循环平稳特性。(The cyclic spectrum of different signals (AM, BPSK, BFSK, DME, etc.) can be directly used to analyze the cyclostationary characteristics of signals.)
