Abstract
A basis expansion model (BEM) for time-varying channels is proposed. It overcomes the effects of Gibbs phenomenon of the widely used complex-exponential BEM (CE-BEM) by using baseline tilting and therefore significantly reduces the modeling error. Theoretical analysis and simulation results show that the modeling error of the proposed BEM is obviously lower than those of the complex-exponential BEM (CE-BEM) and the general complex-exponential BEM (GCE-BEM).
