基带ＯＦＤＭ系统的Ｍ文件，对初学者有很大的参考价值(the code of the article was based on ＯＦＤｍ， have a very high reference value.)

code for sattelite calculaton

基于粒子群算法的无功优化MATLAB源代码，IEEE30节点，希望对大家有帮助(Particle swarm algorithm with reactive power optimization, more practical, we want to help, 14 nodes)

说明：  利用QPSK信号的常数模盲均衡算法，通过同步之后减少误码率(QPSK signals using constant modulus blind equalization algorithm, followed simultaneously reduce the error rate)

在MIMO2*2的无线信道环境下，运用OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，发送信号，经过奇异值分解预编码，调制，在接收端解调，均衡，最终等到估计信号，并计算了整个系统的误码率；(In the wireless channel environment MIMO2* 2, the use of OFDM (Orthogonal Frequency Division Multiplexing) that is an orthogonal frequency division multiplexing, transmission signal, through a singular value decomposition of the pre-encoding, modulation, demodulation at the receiver, equalization, until the final estimated signal, and calculate the error rate of the whole system )

根据干信比调节，生成指定带宽的调频噪声，产生噪声调频信号(According to the dry letter than regulation, to generate a specified bandwidth FM noise, noise FM signal)
