For these examples, we assume that the SUs can perform spectrum sensing perfectly.
In these examples, we assume the two-ray ground propagation model.
In all examples, we assume that the channels are of Rayleigh flat-fading with unit variance.
In our examples, we assume oil and gas prices to be 87$/STB and 3.5$/MSCF, respectively.
In all the examples we assume that the headway time between trains is at least two minutes.
For all examples, we assume that the channel matrices (H r and H s ) have independent and identically distributed Gaussian entries with zero mean and variance 1.
In the following examples, we assume that the initial angle and normalized Doppler frequency estimate errors have uncertainties Δθ = [−3°, 3°] and Δf D = [−0.04, 0.04], respectively.
In numerical examples, we assume that there are three different model types say Model 1, Model 2, Model 3 and five different colors say Color 1,…,Color 5.
In our examples, we assume this lag time to be 7 time units.
In these examples, we assume that the noise level does not depend on stimulus coordinate.
