Single Carrier Frequency Division Multiple Access (SC-FDMA) is a novel method of radio transmission under consideration for deployment in future cellular systems; specifically, in 3rd Generation Partnership Project Long Term Evolution (3GPP LTE) systems. SC-FDMA has drawn great attention from the communications industry as an attractive alternative to Orthogonal Frequency Division Multiple Access …

Broadband Wireless Mobile (3G and 4G) will be the next key developments in wireless communications. Immense interest has been fuelled by large demand for high frequency utilisation as well as a large number of users requiring simultaneous multidimensional high data rate access for the applications of wireless mobile internet and e-commerce. Broadband wireless mobile extends the corporate LAN to co…

Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communications. SDR is viewed as an enabler of global roaming and as a unique platform for the rapid introduction of new services into existing live networks. It therefore promises mobile communication networks a major increase in flexibility and capability. SDR …

Broadband Powerline Communications: Network Design covers the applications of broadband PLC systems in low-voltage supply networks, a promising candidate for the realization of cost effective solutions for “last mile” communications networks. There are many activities surrounding the development and application of PLC technology in the access area, particularly because of strong interest of new ne…

First introduced in 1999, i-mode was the world's first smart phone for Web browsing. The i-mode wireless data service offers color and video over a variety of handsets. Its mobile computing service enables users to do telephone banking, make airline reservations, conduct stock transactions, send and receive e-mail, play games, access weather reports and have access to the Internet. It can offer a …

The expansion and popularity of the Internet, along with the addition of wireless data functionality to wireless networks, has also contributed greatly to the growth of the wireless industry. In fact, the anticipated consumer demand for high bandwidth wireless data is commonly seen as the driving force behind current network upgrades and expansions. The number and types of companies aggressively i…

In the last fifty years, extensive studies have been carried out worldwide in the field of adaptive array systems. However, far from being a mature technology with little research left to tackle, there is seemingly unlimited scope to develop the fundamental characteristics and applications of adaptive antennas for future 3G and 4G mobile communications systems, ultra wideband wireless and satellit…

A state-of-the-art guide to middleware technologies, and their pivotal role in communications networks. Middleware is about integration and interoperability of applications and services running on heterogeneous computing and communications devices. The services it provides – including identification, authentication, authorization, soft-switching, certification and security – are used in a vast ran…

The Software Communications Architecture (SCA) establishes an implementation-independent framework for the development of Joint Tactical Radio System software configurable radios. It specifies the Operating Environment, services and interfaces that applications use. Software Defined Radio: The Software Communications Architecture focuses on the issues and benefits associated with developing a radi…

We are currently in a digital content era. With the increase in circulation of multimedia content globally via the internet it has lead to the need for reuse of content stored in archives; the utilisation of newly stored materials; partially finished broadcasting programmes and finished content. This book proposes to show solutions to these numerous content issues. It will discuss large scale arch…

The impending advent of GSM in the early 1990s triggered massive investment that revolutionised the capability of DSP technology. A decade later, the vastly increased processing requirements and potential market of 3G has triggered a similar revolution, with a host of start-up companies claiming revolutionary technologies hoping to challenge and displace incumbent suppliers. This book, with contri…

The wireless community is on the verge of the standardization of fourth generation (4G) systems. Research has generated a number of solutions for significant improvement of system performance. The development of enabling technologies such as adaptive coding and modulation, iterative (turbo) decoding algorithms and space-time coding, means that industry can now implement these solutions. Advanced W…

The field of telecommunications is becoming ever more complex. In order to manage the new Telecom industry it is necessary not only to understand its 3 main components, namely the end users, the technology and networks, and the business aspects, but also their vital inter-relationships. Complexity leads to uncertainty, and one effect of uncertainty is for people to underestimate the complexity of …
