Cyclic-prefixed orthogonally time multiplexed orthogonal amplitude modulation

Orthogonally multiplexed orthogonal amplitude modulation (OMOAM) is a modulation family unifying numerous modulations date back from 1960s and also many standard-preferable modulations. By converting frequency multiplexing to time multiplexing, orthogonally time multiplexed orthogonal amplitude modulation (OTMOAM) is proposed to explore advantages over the conventional orthogonally multiplexed orthogonal amplitude modulation (OMOAM). Transmitter and receiver system models unifying both OTMOAM and OMOAM are provided, and bit error rate (BER) for both systems are also derived for flat Rayleigh fading channel. Numerical results show that OTMOAM provides lower PAPR and better BER performance in high signal-to-noise power ratio than the conventional OMOAM.
