Abstract :

Orthogonal frequency division multiplexing (OFDM) is a promising multi-carrier modulation technique and has been widely used for wireless communications systems. OFDM is inherently high-bandwidth efficient, but we cannot avoid bandwidth inefficiency to remedy the increased peak-to-average power (PAPR) issue in OFDM systems. In this talk, we consider the bandwidth inefficiency issue of some PAPR reduction techniques for OFDM systems. Two schemes are introduced to cope with the issue. One is null-subcarrierâ??s switching approach and the other is subcarrier group modulation (SGM) approach. Especially, the latter one accomplishes bandwidth efficient communications. Some simulations results are shown and it is unveiled that both approaches are interesting and play an important role for OFDM systems.
