matlab code for bandpass filter

matlab编程规则与技巧，系统的介绍了使用matlab语言的编程用法和技巧，加深了大家对matlab课程的学习。(matlab programming rules and techniques, the system introduces the use of matlab programming language usage and skills, deepened everyone matlab courses.)

说明：  通信系统的仿真,基于matlab的.m文件.详细给出了一种离散信道的源码!(communications system simulation, based on Matlab. M documents. Details are given a discrete channel source!)

很好的程序哦！可以用于混沌系统的同步研究，对于系统参数未知的网络进行估计，很好！(very good！it is very helpful for our study！)

This script illustrates the fading in gmsk under nakagami distribution.A reference paper is also included.

说明：  可用来求解多仓库的车辆路径问题，经测试可直接运行(This program can be used to solve the vehicle routing problem of multiple warehouses, and can be directly run after testing)

three dimensional Plot PSCAD using Matlab

维特比算法，用于对卷积码进行解码，算法最小化汉明距离而不是似然函数(Viterbi algorithm. The Viterbi decoder for convolutional codes.This algorithm minimizes the metric rather than maximizingthe likelihood.)

利用Matlab提供的firhalfband函数设计阶数为16、通阻带容限为0.0001的半带滤波器。 仿真测试滤波前后的信号时域图，绘制滤波器的频率响应特性图。( Matlab provides firhalfband function design of the order number is 16, stopband tolerance of 0.0001 half band filter. simulation test before and after filtering signal time domain graph, drawing filter frequency response characteristics of the figure.)

OFDM系统，包括自适应功率和比特的分配，通过matlab实 现(OFDM systems, including adaptive power and bit allocation, by matlab )
