单蜂窝小区中D2D通信的功率控制算法仿真(Simulation of power contorl algorithm for D2D communication in single cellular cell)

说明：  在数学建模当中，粒子群算法的通用案例，只需要修改核心算子——适应度即可。(In mathematical modeling, the general case of particle swarm optimization only needs to modify the core operator fitness.)

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.

说明：  比较经典的MATLAB教程，文字清晰，适合入门者。(More classic MATLAB tutorial, text clear, suitable for beginners.)
