Radio Wave Propagation

One of the prerequisites for the development of telecommunication services is the<br /> understanding of the propagation of the waves, either acoustic, electromagnetic,<br /> radio or light waves, whi

Radio Propagation Measurement

Radio propagation measurements and channel modelling continue to be of fundamental importance<br /> to radio system design. As new technology enables dynamic spectrum access and higher data rates,<br

qorvo-carrier-aggregation-fundamentals

Mobile operators must continuously pursue cost‐<br /> effective and efficient solutions to meet the high data<br /> demand requirements of their subscribers. Limited spectrum<br /> allocations and non

Principles of Spread-Spectrum Communication

The continuing vitality of spread-spectrum communication systems and the devel-<br /> opment of new mathematical methods for their analysis provided the motivation to<br /> undertake this new edition

Principles of Spread Spectrum

The goal of this book is to provide a concise but lucid explanation and deriva-<br /> tion of the fundamentals of spread-spectrum communication systems. Although<br /> spread-spectrum communication is

Opportunistic+Spectrum+Sharing

Rapid growth of wireless communication services in recent decades has created<br /> a huge demand of radio spectrum. Spectrum scarcity and utilization inefficiency<br /> limit the development of wirel

Multi-Carrier+Spread+Spectrum+2007

Since the principle of multi-carrier code division multiple access (MC-CDMA) was<br /> simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE<br /> International Symposium on

HSDPAHSUPA+for+UMTS+High+Speed+Radio+Access

The first Third Generation Partnership Project (3GPP) Wideband Code Division<br /> Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005<br /> there were 100 open WCDMA networ

Distributed+Quality-of-Service+Support

This thesis is about wireless communication in shared radio spectrum. Its origin and<br /> motivation is ideally represented by the two quotations from above. In this thesis, the<br /> support of Qual

Compressed+Video+Communications

This book examines the technologies underlying the compression and trans-<br /> mission of digital video sequences over networking platforms. The incorporated<br /> study covers a large spectrum of to

Cognitive+Wireless+Network

Cognitive radio has emerged as a promising technology for maximizing the utiliza-<br /> tion of the limited radio bandwidth while accommodating the increasing amount of<br /> services and applications

Cognitive+Radio+Networks

According to the statistics of the Federal Communications Commission<br /> (FCC), temporal and geographical variations in the utilization of the as-<br /> signed spectrum range from 15% to 85%. The li

Baseband+Receiver+Algorithms

The growing interest for high data rate wireless communications over the last few decades<br /> gave rise to the emergence of a number of wideband wireless systems. The resulting scarcity<br /> of fre
