Executive Summary

High Peak-to-Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) signals results in inefficient operations of nonlinear devices used in OFDM systems and high Peak Interference-to-Carrier Ratio (PICR) of received signals degrades Bit-Error Rate (BER) performance of the system. Joint design problem for OFDM systems considering both PAPR and PICR is investigated in this paper. They formulate a joint constrained and a joint weighted PAPR-PICR reduction problems, so that both PAPR and PICR are reduced and the performance of the system is improved.
