本程序通过分析OFDM信号的循环平稳特性，利用循环谱对OFDM信道进行估计。-This procedure by analyzing the OFDM signal is cyclostationary properties, the use of cyclic spectrum of the OFDM channel estimation.

循环谱估计算法，SSCA，FAM，可以运行，结果不错，你值得拥有(Cyclic spectrum estimation algorithm, SSCA, FAM, you can run, and the results are good, you deserve)

2fsk调制仿真产生IQ数据，然后利用循环谱相关算法估计2fsk的Dev，代码完整可用(2FSK modulation simulation produces IQ data, and then uses cyclic spectral correlation algorithm to estimate the Dev of 2FSK. The code is complete and available)
