PERFORMANCE ANALYSIS OF PAPR REDUCTION TECHNIQUES IN MC-CDMA SYSTEM

Abstract

MC-CDMA is the most promising technique for high data bit rate and high capacity transmission in wireless communication. One of the challenging issues of MC-CDMA system is very high PAPR due to large number of subcarriers which reduces the system efficiency. MC-CDMA or (OFDM-CDMA) multiple access has become a most likely technique for future generation broadband wireless communication system such as 4G. Reduction in PAPR have showed the way of consuming less power, improvement in spectral bandwidth, low bit error rate, lesser amount of complexity and cost. This paper describes the various PAPR reduction techniques for MC-CDMA system with used in communication channel and modulation techniques. The result it outcome with high Peak to Average Power Ratio which introduce solemn disturbances for instance lower resolution and reduction in battery life and the performance results is draw in PAPR versus CCDF.
