—In Cognitive OFDM, out-of-band (OOB) leakage of OFDM signal should be suppressed in order to avoid interference to primary signals. Active interference cancellation (AIC) is a novel OOB leakage suppressing technique. In this paper, AIC method for multiple narrow-band primary signals (NPSs) in cognitive OFDM is discussed. We propose a sub-optimal method of(More)
