Measurement Based Determination of Parameters for In-stationary TDL Models with Reduced Number of Taps

This paper proposes a new strategy of extracting parameters for tapped delay line channel models for vehicle to X channels from measurements. The proposed approach is based on an already existing method to derive parameters for a non-stationary tapped delay line model using first-order Markov chains. It will be shown that with a different method of choosing active-taps and the number of taps necessary to regenerate the delay spread of a channel can be significantly reduced. The feasibility of the method will be confirmed using channel sounding measurements.
