摘要

Indoor Doppler measurements in high sensitivity receivers are often biased due to the indoor multipath and user dynamics. The work presented here investigates the relationship between Doppler errors and some key channel parameters. A directional multipath channel model is introduced and some essential channel parameters are defined. In nonsymmetric scattering environments, the Doppler biases are shown to be explicitly related with these parameters. Theoretical simulation and experimental data are analyzed and demonstrated to be consistent.
