Joint Channel Estimation, Equalization, and Data Detection for OFDM Systems in the Presence of Very High Mobility

This paper is concerned with the challenging and timely problem of joint channel estimation, equalization, and data detection for uplink orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying channels. The resulting algorithm is...
