A NGSM for SISO V2V Channels

In this chapter, a novel time-frequency non-stationary non-geometry stochastic model (NGSM) is proposed. To include the line-of-sight (LoS) component, the proposed model generates a non-uniformly distributed tap phase. Moreover, the proposed model can experience variable types of Doppler spectra for different delays. To model the time non-stationarity, the Markov chains are leveraged to capture the appearance and disappearance of paths. In consideration of the non-stationarity in the frequency domain of vehicular communication channels, we further consider that the amplitude and phase of different taps are correlated. Based on the proposed model, some significant statistical properties are derived. Finally, excellent agreement is achieved between the simulation results and the measurement data, confirming the accuracy of the proposed model.
