Abstract :
This paper addresses stochastic modeling of non-stationary small scale fading channels. Referring to the WSSUS assumption for simplified modeling, we model the opposite cases of scatterers correlated in delay and Doppler frequency. Correlated scatterers can be easily incorporated in a sum-of-sinusoids based tapped delay line, thus, enabling a simple realization of a non-stationary channel impulse response.
