Abstract

OFDM (Orthogonal Frequency Division Multiplexing) systems suffer through a critical drawback: The approximately Gaussian-distributed output samples produce high Peak-to-Average Power Ratio (PAPR), which leads to the inter-modulation among sub carrier. It is observe that companding transform is an excessive operation after modulating the OFDM signals, thus companding schemes reduce PAPR at the expense of generating companding Transform.
