A novel linear combination representation aided time-domain smooth signal design is proposed by continuity-enhanced basis signals for the N-continuous orthogonal frequency division multiplexing (NC-OFDM) system. Compared to the conventional NC-OFDM, the proposed scheme is capable of reducing the interference and maintaining the same sidelobe suppression performance imposed with the aid of two groups of basis signals assisted by the linear combination form. Our performance results demonstrate that with a low complexity overhead, the proposed scheme is capable of improving the error performance in comparison to the conventional NC-OFDM, while maintaining the same sidelobe suppression as the conventional counterpart.
