based receiver implementations. In recent years, SCFDE hasbecome a powerful and an attractive link access method forthe next-generation broadband wireless networks [16–18].Because it is essentially a single-carrier system, SCFDE doesnot have some of the inherent problems of OFDM suchas high PAPR.

In the early days of human civilisation, simple optical communication in terms of signal firesand smoke was used. In those days, only limited information could be transferred within lineDistributed Feedback Laser Diodes and Optical Tunable Filters H. Ghafouri–Shiraz# 2003 John Wi[r]

Chapter 1IntroductionA communication system transmits information from one place to another, whetherseparated by a few kilometers or by transoceanic distances. Information is often car-ried by an electromagnetic carrier wave whose frequency can vary from a few mega-hertz to several hundred te[r]

Generation of single frequency radiation from a semiconductor laser based on a special laser module (amplifying laser module) is presented. The multi-mode emission with the spectral bandwidth of 100A0 is converted to single mode one with a narrow bandwidth of 2A0 in the presence of external optical[r]

One way to improve the performance of wireless optical communication systems is the use of channel coding techniques. Several studies have been conducted to study the effect of the use of channel coding techniques in conditions of strong turbulence (Tisftsis, 2008) which is the scenari[r]

QAM overlay links that carry separately broadcast and a DWDM multiplex of narrowcast spectra before combining them close to the node. Such solutions have severe limitations concerning the number of narrowcast channels that can be carried in the forward spectrum and will need to be replaced as narrow[r]
