Abstract—Multi Carrier-Code Division Multiple Access
(MC-CDMA) in multicarrier modulation system is considered
as the new reliable candidate to offer high data transmission in
mobile environment; but the presence of High Peak to Average
Power Ratio (PAPR) is considered as a critical major drawback
since it is present in OFDM-MC CDMA scheme. it constitutes
an obstacle in its use and its presence in non-linear region of the
power amplifier, causing signal distortion by producing an
inefficient amplification power in the transmission system. In
this paper, after review and making comparison with main
current performed Nonlinear Compandique techniques in the
integral context of OFDM and MC-CDMA PAPR reduction
techniques, we propose a novel nonlinear companding
transform (NLT) technique based on the combination of two
recent NCT based techniques named hyperbolic sine function
and the revised exponential companding transform called
(HIS-RECT). By introducing more adjustability in companding
function and an effective trade-off between the PAPR and bit
rate error (BER) performance can be offered to get stable high
power amplified (HPA) and the non affectation of cost in the
system. Results shows that this novel technique approach
outperform existing NTC techniques for MC-CDMA high data
transmission. The 11dB PAPR reduction performance result is
obtained with Bit Error Rate (BER) improved and better Power
Spectral density/bandwidth.
