书籍 Radio Resource Management
In a cellular communication system, a service area or a geographical
region is divided into a number of cells, and each cell is served by an
infrastructure element called the base station through a radio interface.
Management of radio interface related resources is a critical design
component in cel ...
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 ...
论文 Dynamic+Channel+Acquisition
Multiuser multiple-input-multiple-output (MU-
MIMO) systems are known to be hindered by dimensionality
loss due to channel state information (CSI) acquisition overhead.
In this paper, we investigate user-scheduling in MU-MIMO
systems on account of CSI acquisition overhead, where a base
station dynam ...
书籍 Microwave+Mobile+Communications
Nature is seldom kind. One of the most appealing uses for radio-
telephone systems—communication with people on the move—must over-
come radio transmission problems so difficult they challenge the imagina-
tion. A microwave radio signal transmitted between a fixed base station
and a moving vehicle ...

电源技术 利用高压看门狗定时器加强汽车安全系统
 
Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" ...
技术资料 基于PLC的宿舍管理系统设计
为解决学生逃课滞留宿舍,仅靠人力难以监督的问题,文章提出一种以学生课表为中心,基于PLC的宿舍管理系统。每间宿舍配备HMI触摸屏用于学生课表管理,以S7-1214CPLC为主站管理多间宿舍,以STC15单片机为从站采集传感器信息。根据课程表对宿舍进行有课、无课及特殊情况分类管理,辅助宿舍灯光自动控制、楼道灯光控制及损坏检测、防 ...
书籍 EDGE+for+Mobile+Internet
The General Packet Radio Service (GPRS) allows an end user to send and
receive data in packet transfer mode within a public land mobile network
(PLMN) without using a permanent connection between the mobile station
(MS) and the external network during data transfer. This way, GPRS opti-
mizes the us ...
