Digital signal processing techniques for GPS receivers
Abstract
GPS receiver signal processing can be partitioned into three parts: RF signal processing, estimation of In-Phase (I) and Quadrature-phase (Q) signals; and subsequent processing of these I and Q signals. This paper reviews analog RF signal processing. Three digital signal processing (DSP) techniques of I/Q generation (baseband, amplitude sampled IF, and phase sampled IF) are described and evaluated. Typical DSP algorithms for implementing the subsequent processing functions are presented.
