该程序是对单载波频域均衡的仿真，包括用LS算法进行信道估计以及独特字的仿真(The program is the simulation of single carrier frequency domain equalization, including the LS algorithm for channel estimation and the simulation of unique characters.)

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.

用MATLAB写的宽度优先搜索函数，支持障碍设置和四叉树/八叉树的选择，在路径搜索方面有用。(First search function using MATLAB written in width, support the obstacles set up and quadtree/octree useful in terms of route search.)
