Multi-Carrier and Spread Spectrum Systems

Multi-Carrier and Spread Spectrum Systems describes and analyses the basic concepts of the combination of multi-carrier transmission with spread spectrum (MC-SS). The various architectures and the different detection strategies are examined in some depth. Techniques for capacity and flexibility enhancement of multi-carrier systems such as diversity techniques and space-time/frequency coding (STC, STFC) are also analysed. 

Since 1993 different multiple access concepts based on the MC-SS combination for mobile and wireless indoor communications called OFDM/CDMA or MC-CDMA and MC-DS-CDMA, have been proposed. The main differences between these schemes are in the spreading, frequency mapping, and detection strategies. Meanwhile, other alternative hybrid schemes such as OFDM/OFDMA, MC-TDMA, etc. have been deeply studied that benefit from the advantages of multi-carrier transmission.

This book:

·           Covers multi-carrier and spread spectrum and all derivatives of spread spectrum and OFDM systems.

·            Describes not only HIPERLAN but also wireless multi-user systems dealing with OFDM or spread spectrum techniques: 2G IS-95, 3G UMTS, and 4th Generation mobile communications.

·            Provides significant analysis on multi-carrier transmission, from theory to practical implementations  and is therefore invaluable for systems designers.

·            Examines the essentials of all wireless standards based on multi-carrier/spread spectrum technique.

Written in a highly accessible manner this book will provide a unique reference on the topic of multi-carrier spread spectrum, assisting 4G engineers for their implementation.
