采用pscad/emtdc开发质子交换膜燃料电池的模型，可再生能源(pscad/emtec develop proton exchange membrane fuel cell model)

说明：  对三路单音信号合成模拟话音信号进行PCM编码，并采用BPSK调制，通过AWGN信道，接收端采用BPSK相干解调和PCM译码，恢复原模拟信号(PCM coding is used to synthesize analog voice signals from three monotone signals. BPSK modulation is used to restore the original analog signals through AWGN channel. BPSK coherent demodulation and PCM decoding are used at the receiving end.)

这是自由空间路径损耗的代码。里面有多个m文件(This is the code of path loss in free space. There are multiple M files in it.)

快衰落多输入多输出信道中，无信道状态信息的酉空时调制。属于信道发射和接收两端均无信道状态信息的非相干空时码。程序包含一个主程序和一个酉空时信号产生子程序，并给出误比特率。(Unitary space-time modulation without channel state information in fast fading MIMO channels. It belongs to the incoherent space-time code with no channel state information at both ends of the channel transmitting and receiving. The programs include a main program and a unitary space-time signal generation subroutine, and gives the bit error rate.)

超声速静压探针程序，采用有旋特征线法求解旋成体绕流流场，能给出任意马赫数下的壁面沿程压力分布情况，给出壁面静压恢复到自由来流静压的位置；(Supersonic hydrostatic probe program)

802.11a wlan 物理层的matlab仿真源码(Physical layer of 802.11a wlan simulation matlab source)

对GPS协议进行解析，协议采用nema，解析经纬度，时间等信息(The GPS protocol analysis, protocol uses nema, parsing latitude and longitude, time and other information)

本程序采用对一个潮周期中每个潮流矢量的大小、方向分别在长短轴上进行分解，从而计算出其潮流椭率(This procedure uses to one moist cycle in each tidal current vector size, the direction carries on the decomposition separately on the long minor axis, thus calculates its tidal current ellipticity )

说明：  MATLAB实验，实现svm向量机，内含程序代码和数据(Matlab experiment, the realization of SVM vector machine, including program code and data)

说明：  单机器人路径规划仿真，基于栅格地图模型，采用粒子群算法进行路径规划。(Single robot path planning simulation, based on grid map model, using particle swarm algorithm for path planning)
