论文 A Rate Adaptive Channel Estimation Approach
In this paper, we consider the channel estimation
problem in Millimeter wave (mmWave) wireless systems with
large antenna arrays. By exploiting the inherent sparse nature of
the mmWave channel, we develop a novel rate-adaptive channel
estimation (RACE) algorithm, which can adaptively adjust the
numb ...

IntroductionThis document outlines two ty pes of Printed Circuit Board (PCB) antennas used by CSR, which can be used with 2.4GHz radios.■ Inverted-F■ Meander LineIn addition, this document discusses the effect of placing metallic or dielectric materials near an antenna.
无线通信 通过整合硬件分立收发器简化AISG的控制系统
Abstract: This article describes the Antenna Interface Standards Group (AISG) standard in telecommunications and details itshardware implementation. It explains how a fully integrated transceiver such as the MAX9947 can help reduce space and cost, andsolve bus arbitrations in base-station tower eq ...
书籍 Antennas and Propagation
This book has grown out of my teaching and research at the University of Surrey and out of
my previous experiences in companies such as Philips, Ascom and Motorola. It is
primarily intended for use by students in master’s level and enhanced final-year under-
graduate courses who are specialising in ...
书籍 MIMO Wireless Networks
When we started thinking about writing the first edition of this book a few years ago, we had been
working together for more than five years on the borderline between propagation and signal processing.
Therefore, it is not surprising that this book deals with propagation models and design tools for ...
书籍 MIMO+Broadcast+Channel
Due to the asymmetry between the amount of data traffic in the downlink and
uplink direction of nowadays and future wireless networks, a proper design of the
transceivers in the broadcast channel is inevitable in order to satisfy the users’
demands on data rate and transmission quality. This book d ...
技术资料 TE 弹簧夹
Spring fingers (also known as shield fingers,grounding springs or universal ground contacts)are used in almost every small printed circuit board application. A spring finger is a single contact, surface mountable, internal connector. It provides an electrical connection and grounding from EMI noise ...
电源技术 优化输电线路 精确测量电压驻波比(VSWR)
Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss andreflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line imperfections. Thistutorial defines VSWR and explains how it is calculated. Finally, an antenna VSWR ...

This m-file displays the time waveform for the Gaussian pulse function and the first and second derivatives of the Gaussian pulse function for a 0.5 nanosecond pulse width. Other values of pulse widths may be used by changing fs,t,t1. The program uses the actual first and second derivative equations ...
