Abstract:

Sidelobe suppression, or out-of-band emission reduction, in OFDM systems can be achieved via time-domain windowing but this may result in significantly reduced spectrum efficiency. Alternatively, sidelobe cancellation and signal predistortion techniques have been proposed for spectrum shaping, but schemes achieving a good balance between complexity and performance are yet to be developed. In this paper, an efficient and low-complexity technique referred to as "sidelobe suppression with orthogonal projection" (SSOP) scheme is proposed. An analysis of the SNR performance and robustness characteristics of the proposed technique are also presented. Numerical results show that significant sidelobe suppression can be readily achieved with slight receiver performance degradation. © 2012 IEEE.
