Newton法的本质就是不断用切线来近似曲线,因此,Newton法也称为切线方法。本程序用Newton法求解n元正定函数的最小值,例子在程序中。-The essence of Newton method is used constantly to approximate tangent curve, therefore, Newton method, also known as tangent method. This procedure using Newton method to solve n-positive definite function of the minimum value, for example, in the proceedings.

直方图分析
图像的直方图直方图是分布的数据的图形表示。它是一个连续的变量的概率分布的估计,最初是由卡尔 · 皮尔森。[1] 的直方图是列表的频率,示相邻矩形,竖立在离散的时间间隔 (箱子),面积的观测频率成正比的间隔中的表示形式。矩形的高度也是相等的时间间隔,即频率间隔的宽度除以频率密度。直方图的总面积等于数据的数量。

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
