Multicarrier Code Division Multiple Access for Next Generation Broadband Wireless Mobile Communication

Multicarrier Code Division Multiple Access (CDMA) is one of the most promising candidates for radio access in next generation wireless systems. It is a combination of multicarrier modulation [Orthogonal Frequency-Division Multiplexing (OFDM)] and CDMA, which is very effective in combating severe multipath interference, and provides multiple access simultaneously. The objective of this paper is to highlight the challenges posed by the broadband services and the effectiveness of multicarrier CDMA in future generation mobile communication. It presents a comparative analysis of various types of multicarrier CDMA systems. Further, this paper examines the primary issues and problems in detail, providing various solutions to these problems
