书籍 Radio_Frequency_Interference_Pocket_Guide
Thanks for purchasing the RFI Pocket Guide. The
purpose of this guide to help you identify, locate
and resolve radio frequency interference (RFI). It
includes some basic theory and measurement
techniques and there are a number of handy
references, tables, and equations that you may
find useful. The ...
书籍 Space-Time+Processing+for+Wireless+Communications
In this thesis several asp ects of space-time pro cessing and equalization for wire-
less communications are treated. We discuss several di?erent metho ds of improv-
ing estimates of space-time channels, such as temp oral parametrization, spatial
parametrization, reduced rank channel estimation, b o ...
书籍 Stochastic Geometry and Wireless Networks
A wireless communication network can be viewed as a collection of nodes, located in some domain, which
can in turn be transmitters or receivers (depending on the network considered, nodes may be mobile users,
base stations in a cellular network, access points of a WiFi mesh etc.). At a given time, s ...
技术资料 Understanding_the_Basics_of_MIMO
An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals
simultaneously through multiple antennas, while still utilizing a single radio channel. This is a form of
antenna diversity, which uses multiple antennas to improve signal quality and strength of an R ...
书籍 Wireless Communications 2nd Edition
n the first part of this book, we give an introduction to the basic applications of wireless com-
munications, as well as the technical problems inherent in this communication paradigm. After a
brief history of wireless, Chapter 1 describes the different types of wireless services, and works
out the ...
书籍 Conducted+Electromagnetic+Interference
Electricity has been chosen as the most convenient and useful form of energy, due
to its ease of transportation over large distances and easy conversion to other
energy forms. The biggest inconvenience with electricity is that it cannot be stored
and must be utilized at the moment of generation. The ...
