Abstract :
A novel OFDM signal format, polar-OFDM (P-OFDM), is proposed. P-OFDM offers twice as much spectral efficiency as state-of-the-art real-value unipolar OFDM formats. Inherently, the high PAPR is reduced and the numerical evaluation of the BER performance under dynamic-range constraint of optical sources demonstrates superior results.
