Millimeter Wave Vehicular Channel Emulation: A Framework for Balancing Complexity and Accuracy

open access: yesSensors, 2018
We propose a general framework for the specification of a sparse representation of millimeter wave vehicular propagation channels and apply this to both synthetic data and real-world observations from channel sounding experiments.
