Novel DFT-based Channel Estimation Scheme for Sidehaul System

Hun Choe, Sangmi Moon, Intae Hwang

Abstract

Recently, 3rd Generation Partnership Project (3GPP) has developed sidehaul system to cope with the explosively increasing mobile data traffic. The sidehaul system is based on single carrier-frequency division multiple access (SC-FMDA) due to its low peak-to-average power ratio (PAPR). Also, demodulation reference signal (DMRS) is designed to support multiple input multiple output (MIMO). In this paper, we propose the DFT-based channel estimation scheme for sidehaul system. The proposed scheme uses the 2-dimensional minimum mean square error (2-D MMSE) interpolation scheme for the user moving at a high speed. Simulation results show that the proposed channel estimation scheme can improve normalized mean square error (NMSE), error rate and throughput of conventional system.
