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

模拟退火算法
AppWizard has created this TspSA application for you. This application
not only demonstrates the basics of using the Microsoft Foundation classes
but is also a starting point for writing your application.
This file contains a summary of what you will find in each of the files that
make up your TspSA application.
TspSA.dsp
This file (the project file) contains information at the project level and
is used to build a single project or subproject. Other users can share the
project (.dsp) file, but they should export the makefiles locally.
TspSA.h
This is the main header file for the application. It includes other
project specific headers (including Resource.h) and declares the
CTspSAApp application class.
TspSA.cpp

四重奏:一个理论的定理描述的著名四重奏定理";,&……
四方定理描述: 在数论中有一个著名的“四方定理”,它的含义是: 所有自然数至多只要用四个数的平方和就可以表示。 要求: 该题是一个定理,我们不是去证明它,而是要求同学们编程 序来验证该定理的正确性。 输入: 用户从键盘任意输入一个自然数。 输出: 给出满足四方定理中的至多四个自然数。-Quartet theorem Description : Number Theory in a famous "Quartet Theorem," meaning it is : all natural number can use up to four the number of square and can be expressed. Requirements : The title is a theorem, we will prove it, but to require the students programmed to verify the correctness of the theorem. Input : arbitrary user input from the keyboard to a natural number. Output : the Quartet is to meet the theorem up to four natural number.
