摘要: The purpose of this thesis is to present a novel methodcalled "differential threshold exciser (DTE)" to suppressnarrow band interference in CDMA-OFDM transmission system.Also,another threshold exciser , "over-through threshold exciser (OTTE)",is discussed. The two methods use differenttransform characteristics of the interference and information signal to suppress the narrow band interferenceno matter the interference is stationary or nonstationary.The DTE algorithm has nearly the same performance with the OTTE algorithm with less computation complexity than the simple OTTE algorithm. Thus,the DTE algorithm is a simpleand feasible method to achieve its goal.
