Publisher Description: Future broadband wireless communication systems are expected to offer new and powerful services enabling fast transmission rates of several tens of Mbit/s. This is an ambitious challenge, especially for mobile communication systems, since these systems should be able to cope with several time dispersive channels associated with the signal multipath propagation. Moreover, these systems should have high spectral and power efficiencies as well as high capacity and flexibility. Spread spectrum techniques, particularly coded division multiple access (CDMA) techniques allow high capacity and flexibility, continuous transmission requiring low-peak power requirements for the amplifiers, and some robustness against fading and time-dispersion effects associated with the multipath propagation. When employed in prefix assisted (PA) block transmission schemes combined with frequency-domain receiver implementations, they become especially interesting for broadband wireless systems. In Frequency-Domain Multiuser Detection for CDMA Systems, the use of PA block transmission is considered in the context of both DS (Direct Sequence) and MC (Multicarrier) CDMA schemes. The main focus of this publication is the study of frequency-domain multiuser detection techniques with iterative signal detection/decoding techniques, also in combination with estimation and cancelation of nonlinear distortion effects. The receiver structures are suitable to scenarios with high interference levels and strongly time-dispersive channels. |
