摘要
A complex modulated filter bank based narrowband interference detection and suppression method is developed and its performance is studied in a spread spectrum system. The use of an efficient decimated filter bank with a highly selective subband filter prototype, in combination with a newly developed excision algorithm, offers a solution with efficient implementation that gives better performance than the FFT-based reference systems, especially in the presence of strong interference.
