Nakagami-m Distributed Frequency Selective Multipath Fading Channel for MC-CDMA Systems with Imperfect Power Control Condition
Abstract
In this paper a multicarrier Code-division Multiple-access (MC-CDMA) system is proposed. The system is analyzed with a conventional correlator type receiver. Also A new expression of signal-to-interference-noise-ratio (SINR) and bit error rate (BER) for single cell MC-CDMA wireless system over a Nakagami-m distributed frequency selective multi-path fading channel with imperfect power control condition is derived and investigated. The performance of MC-CDMA over the frequency selective multipath fading channel is examined with varying the number of users and, the number of signal propagation path, L,respectively. From the simulation results we have seen that the SINR and BER performance is affected by these parameters. The result of the analysis will provide relevant information to design the physical layer protocol for 4G mobile communications system.
