摘要：

A symmetric extension method for basis expansion modelling (BEM) under a fast-varying channel is proposed. The conventional DFT BEM approach suffers from power leakage and results in a modelling error floor, especially at the channel boundaries. Proposed is a novel symmetric extension method to reduce the leakage power efficiently. Numerical results show that the performance of the proposed channel modelling method is robust under different normalised Doppler frequencies and the modelling errors at the channel boundaries can be eliminated substantially.
