softwarephaselockedloop
在电网电压频率波动或者三相不平衡的情况下,硬件锁相很难准确检测到基波正序的相位。在结合PWM整流器空间矢量解耦控制算法的基础上,将软件锁相环技术应用在PWM整流器控制系统中,并用仿真和实验验证了该方案的可行性。实验结果表明,该方案解决了电网电压频率波动及三相不平衡时的相位同步等问题,并在工程上具有一定参考价值。(Frequency or voltage fluctuations in three-phase unbalanced case, the hardware lock is difficult to accurately detect the fundamental positive sequence phase. In the space vector PWM rectifier with decoupling control algorithm based on the software used in the PWM rectifier PLL control system, and use simulation and experimental verification of the feasibility. Experimental results show that the solutions to address the voltage and frequency fluctuations of the phase unbalanced three-phase synchronization issues, and the project has a certain reference value.)

基于DFT的MIMO-OFDM系统的信道估计算法研究代码
说明： MIMO系统仿真 ＭＩＭＯ技术可Ｗ极大地提升系统吞吐量和有效抵抗多径衰落的影响，被视作ＬＴＥ的核也技术之一。信号检测模块又是ＭＩＭＯ系统中非常重要的一步，因为接收端收到的信号是经历了无线信道衰落影响的信号，与发送端发送的初始值之间差距较大，因此，在接收端首先应进行信道估计求出信道矩阵Ｈ，然后根据该信道矩阵的信息，从接收端还原出发送信号。因此，在ＭＩＭＯ系统中信号检测直接彰响着系统系能的提升。本章将先介绍高移动性ＭＩＭＯ无线信道的建模方法(simulation of MIMO-OFDM communication system)
