Multiband descomposition and recomposition with directional ideal filter.

首先对采样信号进行傅里叶变换，计算出功率谱或幅值谱，然后用功率谱或者幅值谱的数据，计算每一个中心频率的带宽内数据的平均值。(Firstly, Fourier transform is applied to the sampled signal to calculate the power spectrum or amplitude spectrum, and then the average value of the data within the bandwidth of each center frequency is calculated by using the power spectrum or amplitude spectrum data.)

卷积编码和解码器，通俗易懂，误码率低，有BER仿真曲线(Convolutional encoding and decoding, and user-friendly, error rate and low BER simulation curves)

该编程为矩阵与数据分析课的编程作业程序，里面包括matlab的三次样条曲线程序，有Jacobi迭代法和Gauss-Seidel迭代法等(The programming and data analysis for the matrix class programming operations program, which includes the cubic spline curve matlab procedures, Jacobi and Gauss-Seidel iterative method iterative method)

《matlab扩展编程》，一本很不错的matlab进阶学习书籍，网上不容易找到。(" Matlab extension program," a very good matlab advanced learning books, online is not easy to find.)
