在MATLAB仿真环境下进行的QPSK和BPSK的性能仿真，内容较细致(QPSK and BPSK performance simulation in the MATLAB simulation environment, in greater detail)

信号通过信道外编码、信道内编码、交织、去交织、信道内解码、信道外解码的过程，在高斯噪声和突发干扰的影响下通过matlab仿真完成信道在不同干扰下的误码率曲线，分析各编码对误码率的影响。 (The signal through the outer channel coding, in-channel coding, interleaving, de-interlacing, in-channel decoding, channel decoding outside the process, Gaussian noise and burst under the influence of interference by the completion of matlab simulation in different interference channel bit error rate curve of , analysis of the coding of the bit error rate.)

用于INSAR技术的matlab处理程序，包括形成干涉图、去平、滤波、相位解缠等步骤。(a processing basing on matlab which is used for the technology of INSAR.)

使用matlab中仿真实现差分进化算法，可在多目标优化的应用的使用(matlab differential evolution (DE) algorith)

HHT变换中用于边际谱与FFT比较的一个源码。本人亲试，出的图形基本满足要求。你可以下来看看。(HHT marginal spectrum for the transformation of a source compared with the FFT. I pro-test, the graphics basically meet the requirements. You can look down.)

matlab图像处理命令，初级阶段资料，多多自习。(matlab image processing commands, the initial stage of the information, a lot of self-study. )

判断一个点是否在两条线段（或是四个点）所包含的的区域内(Determine a point whether the two segments (or four points) are contained within the area)
