A Decision Metric Approach to PAPR Performance Analysis of an OM-OFDM Transmission

In this paper, a novel method called Offset Modulation (OM-OFDM) is proposed, to control the Peak-to-Average Power Ratio (PAPR) of an OFDM signal. The theoretical bandwidth occupancy of the proposed offset modulated signal is derived. Using this bandwidth occupancy a closed form theoretical Bit Error Rate (BER) expression for an offset modulated transmission is further derived, validated and compared to OFDM. A BER comparison between OM-OFDM and OFDM at a PAPR value of 13 dB, shows that both methods offer similar BER characteristics for Additive White Gaussian Noise (AWGN) channel conditions.
