Energy-Efficient Multicarrier and Multicarrier-CDMA Systems
Design, analysis, and performance of Multicarrier (MC) and Multicarrier-Code Division Multiple Access (MC-CDMA) systems are considered. Specifically, Multicarrier Modulation (MCM) such as Orthogonal Frequency Division Multiplexing (OFDM) is used in these systems with emphasis on energy efficiency. …

Detection and Coding Techniques for Fourth Generation Air-Interfaces based on Multicarrier Modulation
… for the downlink of 4G wireless systems based on multicarrier modulation. Two joint Orthogonal Frequency Division Multiplexing (OFDM) and Code Division Multiple Access (CDMA) schemes have been characterised and compared in respect of their performance in different environments and configurations. …

Interference suppression and diversity for CDMA systems
In code-division multiple-access (CDMA) systems, due to non-orthogonality of the spreading codes and multipath channels, the desired signal suffers interference from other users. Signal fading due to multipath propagation is another source of impairment in wireless CDMA systems, often severely …

Novel multiuser detection and multi-rate schemes for multi-carrier CDMA
… multi-carrier code division multiple access (MC-CDMA) scheme is a promising candidate for emerging broadband wireless systems. MC-CDMA is a hybrid of orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA). The most salient feature of MC-CDMA is that the rate of …
