Abstract:  A high sensitivity navigation receiver based on FPGA and DSP was presented in this paper, which performed to mitigate cross correlations between multiple satellite signals. The hardware was consisted of RF parts, FPGA and DSP. The core chips were SPARTAN3 and TMS320VC5402, which were adapted to process navigation data and calculate user position. The RF Front-End received the navigation signal and convert it to IF signal which was transferred to FPGA. The algorithm of acquisition and tracking of navigation signal were implemented with SPARTAN3. A parallel correlator using three local replica C/A code was developed here, which improved the acquiring efficiency. This system calculated the user position by TMS320VC5402. © 2011 IEEE.

Abstract:  An information identification algorithm (IIA) for satellite navigation system was proposed in this paper. It uses the fuzzy step size least-mean-square (FLMS) adaptive filter and power distributing predominance wavelet packets transform (PDP-WPT) to eliminate the hostile interference in the process of information identification. Compared with the conventional LMS algorithm, the FLMS performs high convergence rate and low steady-state fluctuation error. PDP-WPT was presented to track the interference effectively, which improves the convergence rate of information identification. Simulations were conducted to evaluate the convergence rate and identification capability of the proposed algorithm. © 2011 IEEE.
