Advance Detection Techniques for Beyond 3G Wireless

One of the main challenges that face wireless multimedia communications is spectral limitations. Current second generation (2G) systems cannot support the demanding throughput requirements of the ever increasing wireless services. Third generation (3G) systems, which promised to provide a data rate of 2 Mbps for indoor users and 384 kbps for mobile users, are also unable to support the requirements of bandwidth intensive services such as streaming video. In this paper the spatial processing is investigated to improve date rate provisions in future generation mobile communication systems. Adaptive antenna and interference cancellation are employed for Multicarrier CDMA in order to achieve robust multi-user detection.
