Detection and Tracking of Mobile Propagation Channel Paths

Abstract

In dynamic channel sounder measurements with a moving receiver and/or moving transmitter, propagation paths' parameters show a time-variant behavior. This paper describes a novel algorithm which is able to both detect individual propagation paths and track how these paths evolve with time. The proposed algorithm is capable of estimating the paths' parameters and outperforms the standard snapshot-based algorithm in cases where low accuracy due to resolution limitations in the delay or angular domain is observed. An example based on channel sounder measurements with a moving receiver is given, showing that the algorithm is able to capture the dynamic behavior of the propagation channel.
