Performance of MMSE Receiver Based Multi Input Multi Output-Interleave Division Multiple-Access System with Multi-user Detection Over Frequency Selective Wireless Communication Channel
Code division multiple access system is the most widely used system for multi-user communications. But the performance of CDMA is limited by multiple access interference and inter symbol interference. With CDMA fading is circumvented by the use of inter-leavers placed between FEC and spreading. After the invention of joint Turbo type receivers, extensive studies have been made to mitigate MAI and ISI employing joint detection and decoding. But high complexity of optimal detection precludes its implementation for signal detection.
