Abstract
Multi-carrier code division multiple access (MC- CDMA) is a powerfull modulation technique that is being considered in many emerging broadband communication systems. However the high peak to average power ratio (PAPR) of the MC-CDMA signal, a special drawback of multicarrier transmission, has limited its wider aplication due to inefficient use of power amplifiers. PAPR strongly depends on particular spreading sequences considered for transmission. Therefore, the performance analysis of uplink MC-CDMA for different spreading sequences and for different receivers in the presence of Saleh model of high power amplifier (HPA) is presented. The results of our analysies show that the aplication of Golay codes in conduction with micro statistic multi-user receiver (MSF-MUD) provide significant better result as the other investigated spreading sequences and receivers.
