Abstract
In this paper, a novel nonsinusoidal orthogonal band division modulation method novel nonsinusoidal orthogonal band division modulation method (NOBDM) is proposed. The idea of frequency division multiplexing is used in the nonsinusoidal orthogonal modulation in time domain (NOM). The frequency band of the system is divided into a lot of shoulder-to-shoulder subbands and the NOM are used in each subband. Due to the best energy concentration character of the Prolate Spheroidal Wave Function (PSWF), the modulated signals of different bands are not interfered each other. The novel method not only has the advantages for compensation and bit loading but also reduces the complexity of orthogonal pulse sets design and implementation. The results of the Monte Carlo simulation show that the proposed method has approximate the same BER performance as the old ways. The scheme is suitable for the wire or wireless broadband communication system.
