Abstract

In this paper, we deal with the challenges regarding the provision of Inter Carrier interference (ICI) and Peak-to-Average Power Ratio (PAPR) for the performance evaluation of Multiple-Input and Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM). We propose a Non-linear Companding Technique (NCT) based on the inverse hyperbolic cosine function for PAPR reduction in OFDM symbol. Orthogonality among subcarriers is maintained and PAPR performance is achieved simultaneously by combing NCT and ICI cancellation techniques. Carrier to interference ratio (CIR) remains unchanged and extra Side Information (SI) is not required to recover the original signal as in the case of PTS and SLM techniques. Simulation results support BER improvement over existing methods in Additive White Gaussian Noise channel.
