摘要：One of the major challenges in wireless communication system is increasing complexity and reducing performance in detecting the received digital information in indoor and outdoor Environments. Consequently to overcome this problem we analyze the delay performance of a multiuser with perfect channel state information transmitting data on deep fading environment. In this proposed system, the Wireless Deep Fading Environment (WDFE) creation for causing a Nakagami Multipath Fading Channel of fading figure ’m’ is used to rectify the delay performance over the existing Rayleigh fading channel. In this WDFE receivers received coherent, synchronized, secured and improved signal strength of information using a Multiuser Coherent Joint Diversity (MCJD) with Multi Carrier-Code Division Multiple Access (MC-CDMA). The MCJD in ’M’ branch of antennas are used to reduce the Bit Error Rate (BER) and MC-CDMA method is used to improve the performance. Therefore, in this proposed system we accompany with MCJD and MC-CDMA is very good transceiver for next generation wireless system of an existing 3G wireless system. Overall, this experimental results show improved performance in different multiuser wireless systems under different multipath fading conditions.
