In this paper, a novel method called Offset Modulation (OM-OFDM) is proposed, to control the peak-to-average power ratio 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. Thereafter, the authors present a newly applied decision metric, which is used to compare the offset modulated method to the traditional OFDM transmission.
