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)

OFDM_rece_matlab
一个OFDM符号128个有效符号,插入128个虚拟子载波
符号率(即有效数据率)fsymbol,而发送速率(需要包括虚拟子载波)2fsymbol
输入的数据需要2倍的发送数据率,以便进行内插,实现位定时跟踪,即4倍fsymbol采样率的调制信号
OFDM symbol Nfft=128 points
一个OFDM符号数据点 Nfft*2 = 256 , Guard Interval点 =Ng*2=64
( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier
symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol
input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal
OFDM symbol Nfft = 128 points
a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64

DCT变换:变换域系数选取采用阈值编码,:阈值越小,图像恢复效果越好,但压缩效果差,一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)
