Abstract
A consecutive mean excision (CME) algorithm is used to suppress digital narrowband interference (NBI) in direct sequence spread spectrum (DSSS) systems. The algorithm can offer remarkable interference suppression and its bandwidth is up to 50% of the bandwidth of the desired signal. Based on centrosymmetry of FFT, an improved CME algorithm is proposed. The algorithm can reduce the iterative times and the storage space, and keep the system performance. Both theoretical analysis and numerical simulation show that the proposed algorithm can effectively suppress digital NBI.
