Abstract
- A method called offset modulation (OM-OFDM) is proposed to control the peak-to-average power ratio (PAPR) of an OFDM signal. This reported work demonstrates the significant modulation, structural and performance differences between an OM-OFDM and CE-OFDM method. The OM-OFDM method in addition is able to accurately control the PAPR of a transmission for a targeted BER, which is currently not possible with CE-OFDM. By using a power performance decision metric (D), the OM-OFDM method is shown to offer a 34 and 3.44 dB net power performance gain (at a BER of 10-4) when compared to a CE-OFDM and traditional OFDM transmission for frequency selective fading channel conditions, respectively.
