说明：  LDPC编码的matlab编程 很有参考价值(LDPC coding was useful matlab programming)

rapparport matlab code solution for 4.31

参考3GPP相关标准并根据LTE技术特征和关键特性，对下行链路级进行设计，包含以下步骤：比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道，还需仿真相应的信道模型。收端则是发端的严格逆过程，对接收信号进行一系列处理，得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

计算指数平滑模型预测及预测值与真实值的统计量计算(Exponential smoothing model and prediction value statistic calculation)

Daubechies wavelet coefficients 4 to 8

说明：  一个神经网络工具箱，包括Support Vector Machine等。(a neural network toolbox, including Support Vector Machine other.)

MATLAB的EMD工具箱，主要是对信号进行IMF分解，然后进行希尔伯特变换。得到信号的瞬时频率，并画出能量图。 使用是解压到matlab的work里面即可。(MATLAB toolbox of EMD, decomposition IMF, then Hilbert transform signal. The instantaneous frequency of the signal, and draw the energy diagram. Use extract to matlab can work inside.)

实现快速傅里叶变换，线性调频Z变换，通俗易懂。(This is for students who is major in communication project.)

数字图像处理中利用matlab完成图像的傅里叶变换、放大、直方图变换、中值滤波、小波变换基本功能(Digital image processing complete use of matlab image of Fourier transformation, amplification, histogram transform, median filtering, wavelet transform basic functions )

simulink的数字调制解调仿真程序，详细说明了2ASK，2FSK,2PSK调制解调模块搭建流程，每个模块的功能用途，以及每个模块的参数设置情况。(Digital modulation demodulation of simulink simulation program, and details the 2 ask, 2 FSK, 2 PSK modulation demodulation module structures, processes, the function of each module USES, and each module of the parameter Settings.)
