有限差分法求电场电势

说明：  本压缩包收集了较为经典的几种关于BCH和RS编译码的matlab程序，以及通信系统的仿真等。供大家参考学习，搬运整理而得(This compression package collects several classical matlab programs about BCH and RS coding and decoding, as well as the simulation of communication system. For your reference and study, handling and sorting out)

说明：  多子带自适应算法，能够有较好的鲁棒性以及稳态特性。(The multi-subband adaptive algorithm has better robustness and steady-state characteristics.)

说明：  关于polar code的信息，我认为非常有用。这不是我写的(As for the information of polar code, I think it is very useful. It is not written by me)

是关于生成QAM 仿真的程序码,可以帮助你用编程的方法完成QAM调制解调系统的仿真(it is something about 16-QAM,it can help you simulink QAM with MATLAB )

Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK. Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve. The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one) of the information-bits Weight Enumerating Function (WEF) using A simulation of the convolutional encoder. Once the WEF is estimated, the analytic formula for the BER is used.(Computes BER v EbNo curve for convolutional encoding/soft decision Viterbi decoding scheme assuming BPSK.
