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

Seal加密算法
这种算法是与所谓的印章加密....密封件也使用四个32位寄存器A，B，C和D，其初始值是由n和第k派生表R和T.这些寄存器被修改过几次迭代，每一个都涉及到8发来确定。在每一轮的9位的第一寄存器（无论是A，B，C或D）用于索引表T在T中检索到的值然后被添加到或异或同的第二寄存器的内容：再次之一的A，B，C或D的第一寄存器，然后由圆9的位置错开。在一些回合第二寄存器通过加入或与异或它进一步修饰的（现在的移位）第一个寄存器。后8轮的这一点，A，B，C和D添加到密钥流，每通过添加或具有一定字从S的迭代是通过向A和C依赖于n个附加的值完成异或它掩蔽第一，N1，N2，N3，N4;到底是哪一个取决于的迭代次数的奇偶性。

RFID indoor location identification for construction projects
资源描述This paper presents a lowcost indoor location identification and material tracking methodology for construction
projects using Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) technology. Onsite
location aware information is an emerging area that focuses on automating delivery of spatial information
pertinent to location of materials, workforce, and equipment. This spatial information can be used to derive
knowledge about construction project status. A two-step algorithm is presented to automate the process of
location estimation and material tracking in near-real-time. In this methodology, a number of passive RFID
tags are distributed onsite where work is progressing, and a mobile RFID reader is carried by a worker onsite.
Each passive RFID tag is deployed as a reference point with a known location (landmark) within a predefined
zone. Reference tags of known locations are used to d
