Abstract: Multicarrier code division multiple access (MC-CDMA) is one of the
promising technologies for future-generation wireless networks. It offers high
data rates, protection against frequency-selective fading and efficient utilization
of the spectrum. The peak to average power ratio (PAPR) is very high in MCCDMA
systems. The partial transmit sequence technique (PTS) and the selective
mapping technique (SLM) reduce the PAPR with more computational
complexity. In this study, the NORM technique was used for PAPR reduction in
MC-CDMA systems. The performance of NORM was analyzed with PTS and
SLM in terms of cumulative complementary distribution, power saving gain,
amplifier efficiency, computational complexity and bit error rate. Simulation
results showed that NORM has better PAPR reduction with less computational
complexity.
