图1为均衡带限信号所引起失真的横向或格型自适应均衡器(其中横向FIR系统长M=11), 系统输入是取值为±1的随机序列，其均值为零；参考信号；信道具有脉冲响应： 式中用来控制信道的幅度失真(W = 2～4, 如取W = 2.9,3.1,3.3,3.5等)，且信道受到均值为零、方差(相当于信噪比为30dB)的高斯白噪声的干扰。试比较基于下列几种算法的自适应均衡器在不同信道失真、不同噪声干扰下的收敛情况(对应于每一种情况,在同一坐标下画出其学习曲线): 1）横向/格-梯型结构LMS算法 2）横向/格-梯型结构RLS算法 并分析其结果。(Figure 1 is a band-limited signal caused balanced horizontal or lattice distortion adaptive equalizer (FIR system in which the lateral length M = 11), the system input is the value of a random sequence of ± 1, mean zero reference signal channel has impulse response: Wherein the amplitude of the distortion for the control channel (W = 2 ~ 4, and so as to take W = 2.9,3.1,3.3,3.5), and subjected to a channel with zero mean and variance (equivalent SNR is 30dB) Gaussian white noise. Compare the following types of algorithm-based adaptive equalizer in a different channel distortion, the convergence of different noise interference (corresponding to each situation, draw their learning curve in the same coordinate): 1) landscape/grid- LMS algorithm ladder structure 2) landscape/grid- RLS algorithm ladder structure And analyze the results.)

OFDM频偏估计优化算法代码，次代码文章是2007年硕士毕业优秀论文，具有很高的参考价值。(OFDM Offset Estimation Algorithm optimization code, sub-article code is 2007 graduate Master of excellent essays, have a very high reference value.)

numerical method for averaging

产生两个远程的发送信号,采用归一化处理使其中一个信号有时延,然后求两个接收信号的高阶累积量.(have two long-distance signal transmission, is used to make a treatment in which a signal delay, Then the received signal for the two Cumulant.)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections

产生不同频率、幅度的正弦波信号，叠加后，设计低通、带通滤波器进行正弦信号的谱分析及提取。(The sine wave signals with different frequencies and amplitudes are generated. After superposition, the low-pass and bandpass filters are designed for spectrum analysis and extraction of sinusoidal signals.)
