matlab code for finite element method

汉明码的方针，用MATLAB自带的函数进行，然后进行比较(copare the code )

说明：  matlab,自适应滤波算法，包括LSL,LMS等(matlab, adaptive filtering algorithms, including LSL, LMS, etc.)

Go-Back-N ARQ is a specific instance of the automatic repeat request (ARQ) protocol, in which the sending process continues to send a number of frames specified by a window size even without receiving an acknowledgement (ACK) packet from the receiver. It is a special case of the general sliding window protocol with the transmit window size of N and receive window size of 1.

BUCK电路电感电容的选取，仿真电路，有干扰时的仿真波形(The BUCK conveter)

本文主要介绍了功率谱估计中古典谱估计中的周期图法和现代谱估计中的 AR模型Burg算法，对这两种算法进行了原理说明，并对其进行了仿真，通过结果分析比较其优缺点。 (In this paper, power spectral estimate the Burg AR model algorithm in the the periodogram in classical spectral estimation method and the modern spectral estimation, the principle description of these two algorithms and compare their excellent analysis of simulation results shortcomings.)

说明：  GMSK 信号在衰落信道中的频偏盲估计,学习阶段，大家共同进步(GMSK signal at the frequency of fading channel偏盲estimates, study phase, the common progress of U.S.)

matlab 中微分方程的程序，相当的不错，还包括课件ppt.(procedures in the differential equations matlab, very good, also includes courseware ppt.)

说明：  m序列的产生方法的源代码 matlab仿真 希望初学者有用(m sequence generator method )

This is a complete simulation for illustrating MSK & GMSK modulation techniques spectral Efficiency.
