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.
