| Abstract: | In this paper, a novel approach of narrowband interference (NBI) reconstruction for time-domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) systems is proposed. Exploiting the difference measuring of the adjacent frame heads of TDS-OFDM, the NBI can be accurately recovered and cancelled with high spectrum-efficiency without relying on channel estimation, which improves the robustness of transmission systems. |
