Abstract

This paper investigates the problem of single-tone jamming in orthogonal frequency division multiplexing (OFDM) systems. A frequency-domain estimation and elimination scheme for single-tone interference is proposed. The proposed scheme is independent of any pilot or vacant sub carrier. Simulation results demonstrate that the proposed method is superior to the typical time-domain prediction filter and the frequency-domain threshold-based detection algorithm in most conditions.
