802.11a OFDM MATLAB仿真代码(802.11a OFDM MATLAB simulation code)

These are MATLAB codes for implementing Chebyshev-Type 1 Bandpass and Bandstop filters.

递归极大似然数估计，在实际通信系统仿真过程中非常有用(Recursion number of maximum likelihood estimate, in actual communication system simulation process is very useful )

对连续的单一频率离散序列 ，即k=8。 按采样频率 采样，截取长度N分别选N =20和N =16，观察其DFT结果的幅度谱。 (Discrete to continuous sequence of single frequency, ie k = 8. According to the sampling frequency sampling, truncation length N = 20 N, respectively, and selected N = 16, observed the results of its DFT magnitude spectrum.)
