该程序是我硕士毕业论文《单相并网逆变器》源程序,调试成功的。(直流直接逆变为交流的单相全桥逆变拓扑,有离网并网功能,锁相环过零检测再采用PI.)(This program is my master' s thesis, " single-phase grid-connected inverters," the source, debugging success. (DC-AC inverter direct single-phase full-bridge inverter topology, there are off-grid and network functions, PLL zero crossing detection and then using PI.))

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)
