The channel coding toolbox includes: Channel models: Binary, symmetric channel (BSC)...

说明：  语音信号处理分析，数字图像处理系统，对输入系统的图像及语音加噪去噪(Speech signal processing)

SUPPORTING FILE FOR CONVERT GREYSCALE INTO BINARY STERAM

微波啁啾延迟线设计程序。压缩包中，Chirp_z.m为计算等效电路中的阻抗分布。W_h.m为等效线宽的分布。结合相关的三维设计软件，可以设计出具有线性群时延特性的延迟线。(Microwave chirped delay line design program. Compressed packages, Chirp_z.m distribution for computing the impedance of the equivalent circuit. W_h.m equivalent linewidth distribution. 3D design software, you can design a linear group delay characteristics of the delay line.)

将模糊自适应控制与PID控制算法结合起来，建立模型并利用simulink进行仿真。(Combining fuzzy adaptive control with PID control algorithm, the model is built and simulated in simulink.)

说明：  利用matlab编程进行参数检验，点估计，区间估计，以及非参数检验(Using matlab programming parameter testing, point estimation, interval estimation, as well as non-parametric test)

This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to "capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2. All programs are verified with MATLAB versions 6.0 and above with signal processing and communications toolboxes.(This chapter contains sample programs for determining capacity.
