In this paper, we present a new method called `differential threshold exciser (DTE)' to suppress narrow-band interference in OFDM-CDMA transmission system. Also, another threshold exciser, `over-through threshold exciser (OTTE)', is discussed. The two methods use different transform characteristics of the interference and information signal to suppress the narrow-band interference no matter the interference is stationary or nonstationary. The DTE algorithm has nearly the same performance as the OTTE algorithm with less computation complexity.
