用于读取las格式数据的matlab程序，程序开头已附有使用说明。(Read las data using matlab. Usage instruction is in the beginning of the file.)

控制理论算法在采用状态反馈对目标进行控制时，往往忽略了时滞的存在。时滞往往存在于真实的系统中，而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论，以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)

这是关于目标定位的几种基本算法，包括质心算法、RRSI算法、TOA算法、AOA算法，所有程序均已调通，仿真结果通过。(This is some basic algorithm about target positioning,including barycenter ,RSSI,TOA,AOA algorithm,and all of them were tested successfully!)

matlab程序验证离散时间傅里叶变换的频移性质和卷积性质(matlab program verification discrete-time Fourier transform convolution nature of the nature and frequency shift)

利用matlab软件设计并仿真下面的无线通信系统。模拟信源为单音频信号。模拟调制方式为DSB。信道为多径信道（仿真中2径），信道中噪声为加性高斯白噪声。采用相干解调接收。画出了解调器输出端性能曲线与点信噪比SNR的关系。 (Software design and simulation using matlab the following wireless communication systems. A single analog audio signal source. Analog modulation of DSB. Channel multi-path channel (simulation 2 diameter), channel noise is additive white Gaussian noise. The use of coherent demodulation receiver. Draw the output of the demodulation performance curve and the point of the relationship between signal to noise ratio SNR.)

turbo 编译码器，适用于LTE标准。 LTE标准需要100Mbps，此仿真采用并行交织译码，可以达到LTE标准(turbo encoder and decoder for LTE standard. LTE standard requires 100Mbps, the simulation mixed parallel decoding, can achieve the LTE standard)
