决策树是用二叉树形图来表示处理逻辑的一种工具。可以直观、清晰地表达加工的逻辑要求。特别适合于判断因素比较少、逻辑组合关系不复杂的情况。...

应用背景阅读c和指针时，初学者都会被一些疑问所困扰，我将一些亲测可用的问题答案代码放上来了。关键技术包含代码较全，比课后答案附录要全

subpixel motion architecture

此程序计算凸壳、 Delaunay 三角剖分、 alpha 形状和 Voronoi 卷，使用增量式算法和精确的算法。若要安装，请键入"做"，可能调整生成文件后。

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
