用PTS方法降低OFDM信号中高PAPR的MATLAB仿真源代码，很实用哦(PTS method used to reduce the high PAPR of OFDM signal simulation of the MATLAB source code, it is practical Oh)

用窗函数法设计线性相位FIR低通滤波器。要求通带截止频率ωc=π/4，单位脉冲响应h(n)的长度N=23。绘出h(n)及其幅频响应特性曲线(Window function with linear phase FIR design a low pass filter. Required pass-band cutoff frequency ωc = π/4, unit impulse response h (n) of length N = 23. Plot h (n) and frequency response curves)

实现多个混合信号的盲源分离！程序简单、易懂！适合初学者学习！(Multiple mixed-signal blind source separation! The program is simple, easy to understand! Suitable for beginners to learn!)

In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.
