O knihe

Multi-Carrier Direct-Sequence Code Division Multiple Access (MC-DS-CDMA) is a multiplexing technique that combines the advantages of both multi-carrier modulation and DS-CDMA. Among them are high system flexibility, high data rate transmission, high bandwidth efficiency and fading resilience. Adopted as an option for the down-link transmission in the CDMA2000 third Generation (3G) cellular standard, MC-DS-CDMA is also one of the potential candidates for the future fourth Generation (4G) broadband wireless systems. When designing receivers for MC-DS-CDMA mobile wireless systems, two main problems must be taken into account. Firstly, the Multiple Access Interference (MAI) caused by other active users greatly limits the system capacity. Secondly, the multi-path fading of mobile radio channels which highly degrades the system performance. Therefore, in this book, our objective is twofold. Firstly, we aim at designing new receivers for MC-DS-CDMA systems that are able to suppress the MAI. Secondly, as receiver design usually requires the explicit channel estimation, we intend to develop new techniques to estimate time-varying fading channels.
