Inter-Carrier Interference Estimation in OFDM Systems With Unknown Noise Distributions

There are a number of approaches to estimating carrier frequency offset (CFO) that causes inter-carrier interference (ICI) in orthogonal frequency division multiplexing (OFDM) systems: self-cancelation method, the extended Kalman filter (EKF), particle filter, H infin filter (HF), etc. In particular...
