A study on low-complexity receiver of NCSP-OFDM for sidelobe suppression

N-continuous symbol padding orthogonal frequency division multiplexing (NCSP-OFDM) is a modulation technique for sidelobe suppression, which adds the correction symbol only into the guard interval to enable the seamless connection of OFDM symbols. NCSP-OFDM requires the calculation of an inverse matrix per channel estimation, and so its computational complexity is large. This paper considers low-complexity receivers of the NCSP-OFDM. Numerical experiments are conducted to evaluate its performance compared with conventional NCSP-OFDM receiver.
