Abstract

This paper presents a frequency estimator based on carrier detection scheme and MUSIC algorithm which can be used for a BPSK direct sequences spread spectrum signals systems . Under non-cooperative circumstance, the nonlinear carrier detection method is used to detect the presence of DS signal, and it created detectable components of the multiplies of the carrier frequency .Combined with MUSIC algorithm , the carrier frequency can be accurate estimated without the prior knowledge of received signals. The theory of proposed algorithm is introduced in this paper and simulation results have shown that the algorithm has good estimation performance even when signals are buried in strong background noise
