Iterative Turbo Channel Estimation for OFDM System over Rapid Dispersive Fading Channel
— Current OFDM systems assume the channel is not time varying within one OFDM frame, and use channel estimates obtained from preamble or pilots for data symbols within the same f...

Iterative channel estimation and turbo equalization for time-varying OFDM systems
We develop a new receiver for orthogonal frequency division multiplexing (OFDM) systems in time-varying channels by embedding channel estimation in a low-complexity block turbo eq...

Frequency Offset Tracking for OFDM Systems via Scattered Pilots and Virtual Carriers
— In this paper, we propose a new carrier frequency offset (CFO) tracking algorithm for orthogonal frequency division multiplexing (OFDM) systems. Assuming that the channel remai...
