A novel method is proposed to acquire the signal parameters for Global Navigation Satellite System (GNSS). This method utilizes discrete wavelet transform (DWT) to divide the wavelet space, indicating that the wavelet transform is better in de-correlation ability and signal acquisition performance. Simulations and experiments demonstrate that the proposed method can improve performance in shorten...
This paper utilizes a novel evolutionary approach to proceed with signal acquisition in Global Navigation Satellite Systems (GNSS). The method controls search space bound of frequency shift and code delay to shorten signal acquisition time. Simulation results show that the proposed scheme can acquire more accurate signal parameters and take less signal acquisition time than the traditional method.
Adaptive antenna processing has been widely applied to GNSS interference mitigation. Nevertheless, a great variety of uncertainties exist in array signal processing, such as array gain, phase, antenna location and mutual coupling, etc. These uncertainties in array system are what concern designers in optimizing their algorithms. The proposed approach is presented as a solution by appending an adaptive...
