应用背景Massive multiuser MIMO (MISO): ◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50) ◮ coherent, but simple, processing ◮ Potential to dramatically improve rate & reliability ◮ Potential to drastically scale down TX power ◮ Not only theory, at least one known testbed (64× ∼10) 关键技术 Massive MIMO Operation Not enough resources for pilots & CSI feedback, so operate in TDD. ◮ On the uplink, ◮ acquire CSI from uplink pilots and/or blindly from data ◮ detect symbols ◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal ◮ On the downlink, ◮ use CSI obtained on the uplink ◮ make necessary adjustments based on reciprocity calibration ◮ apply multiuser MIMO precoding ◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ... ◮ MRC/MRT operation ◮ intracell interference will appear as

在inuxl ubantu系统下的QT运行，一个简单的c++绘图板的编制，能够满足正常情况下的图形的绘制

本程序模拟细胞的自我繁殖，你会看到一个柔软的细胞诞生在电脑屏幕上，然后随着各个分子的撞击，细胞开始分裂，经过一段时间的演化，这个细胞会在溶液中把自己复制，然后这个过程会继续进行……。这种自我复制是在人工化学的基础上进行，比起原来的基于细胞自动机的自我复制更加形象逼真-the cell simulation of self-reproduction, you will see a soft cell birth on the computer screen, and then with all the percussive elements, cell division, after a period of evolution, the cells in the solution themselves copied, and then the process will continue ... . This self-reproduction of the artificial chemical basis, compared to the original cell-based automatic machine self-replication more vivid
