Abstract

In this paper we address two problems. The weak signal process and navigation estimation. The assisted information is used in long signal integration so as to narrow the search space and to enhance the sensitivity of signal process. A new algorithm is proposed to estimate position robustly when the lower signal-to-noise ratio and distorted signal due to multipath reflection. Test results are given to show the efficiency of the methods.
