channel estimation combined with ici self cancellation scheme and unscented kaman filter

A well-known problem of the Orthogonal Frequency Division Multiplexing (OFDM) syste for mobile environment is the fading channel which degrades the system performance. Many methods have been proposed for channel estimation such as LS (Least Square), MMSE (Minimum Mean Square Error), Kalman Filter.…A fading channel with Doppler effect from the moving of receivers degrades system because of complicated changes and hard estimation. That is why traditional estimators do not have good performance. This paper introduces two new solutions of channel estimation for reducing Doppler Effect.
