This program uses matlab to fullfil QPSK and demodulate QPSK.

基于matlab的DSP调试方法，不错，很有用(Matlab)

说明：  it is matlab source code implemeted in Matlab 7.6. this is utilized in matlab.

说明：  改进后的BP神经网络，可以用于模型的优化和预测(The improved BP neural network can be used for optimization and prediction models)

自己写的人工蜂群算法，内带混沌搜索性质，主函数为funqun1，可随意改适应度函数，fitness。该程序简单易懂，方便修改，并且附有程序说明及相关参考论文，也附有本作者的联系方式。(Write your own artificial bee colony algorithm, with the chaotic nature of the search, the main function of funqun1, free to change the fitness function, fitness. The program is simple to understand, easy to modify, and with reference to the program description and related papers, but also with the author s contact information.)

主要实现一无人自行车的控制自主导航，可对导航与控制进行说明(The main achievement of a bicycle control unmanned autonomous navigation, navigation and control can explain)

说明：  s1 is the M-file description of the SIMULINK system named s1. The block-diagram can be displayed by typing: s1. SYS=s1(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型 (Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details: op_channel = additivenoise(input_signal) mathematical Model: s(t) input signal to channel (=sig_ip) n(t)additive random noise process added by channel (=noise_mat) a(t) attenutation factor , here it is taken as random(=att_fact) out put signal r(t) = a .* s(t)+ n(t) an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal )

TSP问题蚁群算法通用MATLAB源程序(TSP problem ant colony algorithm universal MATLAB source)

在一个自己设置的已知障碍的环境下，用势场法做路径规划，起点，目标位置都是已知。我用matlab做的(themselves in a set of known obstacles to the environment, with potential field do path planning, the starting point, target locations are known. I used Matlab to do)
