遥感中关于孔隙率/透过率计算的代码(适用于连续植被和离散植被)
叶面积指数估算中,关于孔隙率计算的代码,考虑了不同的树冠形状(椭圆形、圆锥形、圆锥+椭圆形),并且可基于孔隙率估算叶面积指数和聚集指数。代码包含了连续植被(比尔定律)、和离散植被的情况,离散植被中假设树干在空间上满足随机分布。使用时请引用文献:尹高飞, 柳钦火, 李静, 曾也鲁, 徐保东. 树冠形状对孔隙率及叶面积指数估算的影响分析. 遥感学报, 2014, 18(4), 752 – 759.

massive mimo Fundamentals, Opportunities and Challenges
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
