Channel-Coding

本函数计算hankel函数一致展开中的变量(This function calculation hankel function unanimously expand the variable)

此文件包括mynlms和myrls，编程简单有效，是很好的程序(This file to include mynlms and myrls programming is simple and effective is a good program)

Discrete Cosine Transformation

μ律PCM编码，小信号放大，大信号缩小，非均匀量化实现的一种方式，实用。(μ-law PCM coding, small signal amplification, large signal narrow, one way to achieve a non-uniform quantization, and practical.)

ANC算法的前馈实现，它可以实现噪声的消除，有相关的做这个的人也可以跟我交流，我遇到问题了。。13548074570(the anc used feedforward)

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.)
