HIS-RECT Nonlinear Compandique Technique for MC-CDMA MIMO Transmission

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.
