详细讲述了∏/4-DQPSK调制和解调原理,并提供了matlab实现的代码(Detail the Π/4-DQPSK modulation and demodulation, and provides a matlab implementation of the code)

这是一个关于LDPC中的GIRTH4-COUNT的代码！( This program can produce the Parity Check Matrices of girth4-count codes, while Ref. remindes you that these codes are not good as the LDPC codes IEEE802.16e for continuous bits errors. )

LS-estimation, yule walker equation, levinson durbin algorithm

高斯混合模型的核心计算方法，matlab里可直接调用(Core calculation method based on Gaussian mixture model, matlab years can be called directly)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。 此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 ( This is a space-time block coding based on the MIMO_OFDM Communication System Simulation and Design. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training symbols such as communication channel estimation module.)
