验证可用，有信道编码，调制，信道估计等，ldpc码的编解码实现。( Verification is available, Channel coding, modulation, channel estimation, Codec ldpc code implementatio.)

说明：  ％ 生成三个正弦函数并计算其幅度谱 属于MATLAB基础性的应用( Generate three sine function and calculate its amplitude spectrum belongs to the basic MATLAB Application)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
