Advanced differentially coherent code acquisition in jamming

Abstract

In this paper we consider code timing acquisition in the DS-CDMA communication system. Recently, traditional MUSIC utilizing differential correlations, DC-MUSIC, was proposed. Here DC-MUSIC is applied in different jamming scenarios and several channel environments. Simulation results indicate a clear improvement in acquisition performance compared to traditional MUSIC, conventional and differentially coherent acquisition schemes. In addition, DC-MUSIC is found to be a robust scheme due to the possibility of coherent integration also in the case of jamming.
