空时分组编码(STC)就是在空间域和时间域两维方向上对信号进行编码,是MIMO技术里面十分重要的一个环节。(Space-time block coding (STC) is in the space domain and time domain two-dimensional direction of the signal coding, MIMO technology, which is very important aspect.)

通过matlab仿真工具仿真分析了APSK调制方式在典型的加性高斯白噪声下的传输性能(Through simulation matlab simulation tool analyzes APSK modulation in a typical additive white Gaussian noise transmission performance)

基于普通的SLM方法降低OFDM的PAPR，并验证了M（子载波数）的作用(reduce the PAPR of OFDM)

这是一个基于PR控制的单相逆变器，实现对交流量的无静差跟踪(This is based on a single-phase inverter PR control, realize no static difference to cross flow)

用guide编的matlab界面,可以点击图像任意位置截取一小块(Guide prepared by the matlab interface, you can click the image anywhere on the interception of a small piece of)

LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。 (LDPC Coding with PSK modulation in Rayleigh fading channel Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements. In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.
