巴特沃斯带通滤波器，简单实用，matlab(Butterworth bandpass filter, simple and practical, matlab)

衰落信道参数包括多径扩展和多普勒扩展。时不变的多径扩展相当于一个延时抽头滤波器，而多普勒扩展要注意多普勒功率谱密度，通常使用Jakes功率谱、高斯、均匀功率谱。( The fading channel parameters include multipath spreading and Doppler spreading. The time-invariant multipath extension is equivalent to a delay-tap filter, while the Doppler spread should pay attention to Doppler power spectral density, usually using Jakes power spectrum, Gaussian, and uniform power spectrum.)

SOQPSK调制，根升余弦滤波器源代码，用于初学者的使用和学习(SOQPSK modulation,root-raise cosine filter to use and study for a new user)

The source code is the best neighboring matching method, which will find out a best 16x16 macro block to conceal the lost macor block. this code is written by Matlab.

TSP问题（又名：旅行商问题，货郎担问题）遗传算法通用matlab程序 D是距离矩阵，n为种群个数 参数a是中国31个城市的坐标 C为停止代数，遗传到第 C代时程序停止,C的具体取值视问题的规模和耗费的时间而定 m为适应值归一化淘汰加速指数,最好取为1,2,3,4,不宜太大 alpha为淘汰保护指数,可取为0~1之间任意小数,取1时关闭保护功能,建议取0.8~1.0之间的值 R为最短路径,Rlength为路径长度( TSP problem (also known as: traveling salesman problem, traveling salesman problem) genetic algorithm generic matlab program D is the distance matrix, n is the population number of parameters a C coordinates of the 31 cities to stop algebra, genetic to C on behalf of the program stops, the specific values ​ ​ of C depending on the size and time-consuming, m alpha for the fitness value of the normalized phase-out acceleration index, and is best taken as 1, 2, 3, 4, and not too much eliminated the protection index, it is desirable for any decimal between 0 and 1, taking 1:00 off the protective function, it is recommended to take a value between 0.8 to 1.0 R for the shortest path, Rlength for the path length)
