此包中装有数字喷泉码之一LT码基于鲁棒孤波分布的编译码及测试文件。(This package is equipped with one digital fountain code encoding and decoding LT code and test files based on robust solitary wave distribution.)

这是一种改进的粒子群优化算法，通过简单的测试函数验证(This is an improved particle swarm optimization, through a simple test function verification)

语音信号的先行预测编码LPC 低频率语音编码算法研究及其实时实现(Voice signal of the first predictive coding LPC low-frequency speech coding algorithm for real-time implementation)

说明：  16Qam的Matlab/Simulink仿真系统，包含匹配滤波，载波恢复，位定时恢复等个重要模块，加深对16Qam调制解调系统的理解(16Qam the Matlab/Simulink system, matched filtering, carrier recovery, rehabilitation Timing important module, the better modulation and demodulation system 16Qam understanding)

信号、图像对其求傅里叶变换时很普遍的频域分析，本程序提供对一维信号进行傅里叶变换，提出单边、双边变换！(Signal, images of their demand is very common when the Fourier transform frequency domain analysis, the program provides one-dimensional signals, Fourier transform, the unilateral, bilateral transform!)

MATLAB CODE MRI This is a demo code for mri

覆盖保存是WSN的一个基本质量要求。选择一个最佳的簇头，以满足长时间的监视区域的完全覆盖。使用覆盖意识的方法来选择簇头，而不是基于能量的方法，可以增加场景有效时间。(WSN coverage preservation is a basic quality requirements. Choose one of the best cluster head in order to meet long surveillance area completely covered. Awareness of the methods used to select the cover cluster head, rather than energy-based method, can increase the effective time of the scene.)
