This is a matlab code which deals with TSP problem. This is done using ant colony algorithm. In this problem each city gets visited once and a shortest path is obtained.

base implementation of MD4 family style digest as outlined in "Handbook of Applied Cryptography", pages 344 - 347.

 结合理论课讲解基于Matlab建立不同信道模型：高斯信道、Rayleigh信道，Recian信道及多径衰落信道模型；  给出QAM/GMSK调制方式下在上述信道模型下的误码率性能分析，分析比较两种调制方式的优缺点；  分析信道参数、信噪比对误码率性能的影响； (Based on Matlab, we construct different channel models: Gaussian channel, Rayleigh channel, Recian channel and multipath fading channel model. The error rate performance analysis of QAM/GMSK modulation mode under the above channel model is given, and the advantages and disadvantages of the two modulation modes are analyzed and compared.  Analysis of channel parameters, signal to noise ratio on the impact of bit error rate performance )
