Abstract

This paper presents a technology to deals with the tracking performance of a timing recovery loop for dynamic circumstance GPS receiver. Based on Lagrange interpolation theory authors propose a data interpolation control method suitable for software radio. In our scheme, traditional code fast acquisition algorithm was employed to estimate timing error which has high estimate accuracy. The timing correction is performed by the interpolating filter, which is derived from the timing error detector. The carrier phase tracking can be adjusted precisely by selecting interpolating filter orders such as linear or non-linear. The simulation shows that the timing error recovery has high tracking precision, fast acquisition and keep track performance under high dynamic circumstance.
