Abstract
Time-varying channel degrades the performance of LTE-Advanced system due to the Intercarrier Interference (ICI) and imperfect channel estimation. In this paper, we propose a practical strategy by bit-interleaving preprocessing in transmitting part for Doppler diversity in high-speed scenario. Time-varying channel frequency response and effect of coding rate to this algorithm are analyzed. In addition, to evaluate the performance of the proposed strategy, it is implemented into LTE-A system and simulated. The results show that the strategy can achieve significant performance enhancement in high-speed scenario.
