Abstract

There are no known techniques for the real-time generation of OFDM signals with low peak values when the number of carriers is large and the data rates are high. This paper presents a heuristic algorithm that reduces the peak power to mean power ratio of a 256 carrier AM-OFDM signal to typically less than 2.5dB and always less than 4.2dB. This algorithm can be implemented in real time using commercially available FFT/IFFT integrated circuits. Furthermore, AM-OFDM results in receiver simplification. The low peak power to mean power ratios achieved offset the S/N disadvantage of AM.
