Abstract
Multi Carrier-Code Division Multiple Access(MC-CDMA) in multicarrier modulation system is consideredas the new reliable candidate to offer high data transmission inmobile environment; but the presence of High Peak to AveragePower Ratio (PAPR) is considered as a critical major drawbacksince it is present in OFDM-MC CDMA scheme. it constitutesan obstacle in its use and its presence in non-linear region of thepower amplifier, causing signal distortion by producing aninefficient amplification power in the transmission system. Inthis paper, after review and making comparison with maincurrent performed Nonlinear Compandique techniques in theintegral context of OFDM and MC-CDMA PAPR reductiontechniques, we propose a novel nonlinear compandingtransform (NLT) technique based on the combination of tworecent NCT based techniques named hyperbolic sine functionand the revised exponential companding transform called(HIS-RECT). By introducing more adjustability in compandingfunction and an effective trade-off between the PAPR and bitrate error (BER) performance can be offered to get stable highpower amplified (HPA) and the non affectation of cost in thesystem. Results shows that this novel technique approachoutperform existing NTC techniques for MC-CDMA high datatransmission. The 11dB PAPR reduction performance result isobtained with Bit Error Rate (BER) improved and better PowerSpectral density/bandwidth.
