Abstract

In this paper we discussed the realization of narrow-band interferences(NBI) suppression in direct sequence spread spectrum using frequency-domain algorithm, given the block diagram of the algorithm used in the system and carried out computer simulation. The analysis and simulation result indicate that the frequency-domain algorithm is more efficient than that based on commonly used LMS algorithm for the purpose of cancellation of NBI. The implementation of the system used for narrow-band interferences suppression is also specified in detail. This system is based on TMS320C6201.
