Abstract
Constant envelope orthogonal frequency division multiplexing (CE-OFDM) has been proposed to overcome the primary drawback as high peak-to-average power ratio (PAPR) in original OFDM at the cost of considerable out-of-band emission. The novelty of this contribution is that the concept of N-continuous signaling is integrated with CE-OFDM in order to suppress the sidelobe. More specifically, the scheme advocated is capable of enhancing the continuity between adjacent CE-OFDM symbols and their higher order derivatives. Moreover, the related signal-to-interference-plus-noise ratio (SINR) of the proposed scheme is analyzed in this paper. The performance results show that the sidelobe suppression can be achieved with slight cost of bit-error rate (BER).
