Transmission+Systems+Design+Handbooks

Public telephone operators and new independent wireless operators through-<br /> out the world are deploying wireless access in an effort to drastically reduce<br /> delivery costs in the most expensi

Transmission Techniques for 4G Systems

Fourth Generation (4G) wireless communication systems aim to allow peak data<br /> rates in the range of 1 Gbps for nomadic access and 100 Mbps for vehicular mobil-<br /> ity. 4G aims to support curre

Time-Varying Channels

Wireless communications has become a field of enormous scientific and economic interest. Recent<br /> success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless<

The+Telecommunications+Handbook

Changes in telecommunications are impacting all types of user<br /> group, which include business users, traveling users, small and<br /> home offices, and residential users. The acceptance rate of te

The Mobile Multimedia Business

The first practical examples of mobile communications were used in many countries like<br /> the USA, the UK and Germany in military services, and played a significant role in the<br /> First World Wa

The 3G IP Multimedia Subsystem (IMS)

When 3GPP started standardizing the IMS a few years ago, most analysts expected the<br /> number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were<br /> ready (3GPP Re

Telecommunications+Networks

Rapid progress in information and communications technology (ICT) induces<br /> improved and new telecommunications services and contributes greatly to society<br /> in general and to vendors and netw

Telecommunications Regulation

Regulation is a pervasive feature of the telecommunications services industry today. Government-appointed regulators and judicial or quasi-judicial bodies oversee it in countries at all stages of ec

Technology+Trends+in+Wireless+Communications

The use of mobile devices now surpasses that of traditional computers: wireless<br /> users will hence soon be demanding the same rich multimedia services on their<br /> mobile devices that they have

Spectrum+Sharing+Between+Radars

Radio frequency spectrum is a scarce and critical natural resource that is utilized for<br /> many services including surveillance, navigation, communication, and broadcast-<br /> ing. Recent years ha

Spectrum+Access+and+Management

The radio spectrum is one of the most precious resources which must be managed<br /> to ensure efficient access for the wireless communication services which use it. The<br /> allocation and managemen

Space-Time+Processing

Driven by the desire to boost the quality of service of wireless systems closer to that afforded<br /> by wireline systems, space-time processing for multiple-input multiple-output (MIMO)<br /> wirele

Software+Radio

Software Radio (SR) is one of the most important emerging technologies for the<br /> future of wireless communication services. By moving radio functionality into<br /> software, it promises to give f
