Abstract

Adaptive filtering (AF) acquisition scheme has been proved to be an effective pseudo-noise (PN) code acquisition in DS-SS system, which is especially useful to long PN code acquisition in low Signal Noise Ratio (SNR) environment [1]. In order to make use of this scheme in those PN code acquisition systems with data modulation, a modified adaptive filtering method is proposed in this paper, where the effect of polarity reversion caused by data modulation on PN code is removed by employing absolutely successive difference technique in both the received signals and local generated PN code. Compared with AF acquisition scheme, even with data modulation, the proposed method can attain almost similar acquisition performance, which is tested by simulations.
