基于greedy DSATUR 的经典着色程序(Given a graph, vertex coloring is the assignment of colors to the vertices such that no two adjacents vertices share the same color. Vertex coloring problem is NP-hard for general graphs. However for some specific graph classes there are some positif results. For example by definition we can trivially color a bipartite graph using two colors.)

对光限制因子逐渐变大的波导进行光传输仿真(Simulation of the light transmission optical waveguide limiting factor becomes larger)

RD 算法----SAR点目标仿真 结果还是比较不错的。(RD algorithm---- SAR point target simulation results is quite good.)

this is about DTFT.DTFT s matlab code and it is for Discrete time fourier transform.

瑞利信道仿真，用于ofdm，mimo系统中，望大家下载(Rayleigh channel simulation for ofdm, mimo system, hope you download)

power systems-lamda iteration

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据(The introduction was done with the principle of the QPSK modulation and demodulation in digital communications, a script was written by using Matlab program to carry out a simulation of the QPSK communication system ,which contains the concrete realization of transmit and receive process. The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise, spectral analysis of each module is also done, the results obtained with theoretical results in the main, which provides an effective frame of reference for understanding the performance of QPSK systems, and the practical application in the system to make further designed.)

实验结果表明该算法对非冲击噪声效果良好。 lx_main为主程序，NS_lxwz为噪声估计模块，lxG_wz为增益估计模块，noise_sound为测试用含噪语音。 算法原理参见本人的文章《一种引入延迟的语音增强算法》。(Experimental results show that the algorithm for non-impulsive noise effect is good. lx_main the main program, NS_lxwz for the noise estimation module, lxG_wz for the gain estimation module, noise_sound to test the noisy speech. Algorithm theory see my article " delay the introduction of a speech enhancement algorithm." )
