Abstract

This paper introduces a novel channel prediction technique for OFDM/FDD system to support adaptive modulation and coding (AMC) scheme over rapidly time-varying multipath fading channel. Most channel prediction techniques assume that there is no channel variation in the predefined time duration, e.g., a slot. As a result, those techniques can not compensate the degradation of packet error rate (PER) performance resulting from the rapid variation of channel over the slot duration. In this paper, we propose a novel channel prediction technique that considers the time-varying nature of channel over the duration of interest. Simulation results show that the AMC scheme of OFDM/FDD system utilizing the proposed channel prediction technique can guarantee the target PER of 1% without any loss of system throughput compared with the case supported by the conventional channel prediction under ITU-R Veh A 30km/h.
