Abstract

In this paper the performance analysis of multicarrier spread spectrum system combining with UWB (ultra-wideband) techniques operating in multipath frequency selective fading channel is investigated. The multipath fading model is characterized by Nakagami-m statistic distributed. We propose and derive the model of an MC-CDMA (multi-carrier coded-division multiple-access) systems operating in correlated Nakagami-m fading channel. The average BER (bit error rate) is calculated and compared to the special case of the published results. The results from this paper can be implied to approve the system performance for the UWB system combining with MC-CDMA systems in wireless communication systems. Especially, it is worthwhile noting that the fading parameter of the Nakagami- m distributed significantly dominated the system performance of the UWB system accompany with MC-SS signaling under fading environments.
