Abstract: A multiple-input multiple-output (MIMO) communication system combined with the orthogonal frequency division multiplexing (OFDM) modulation technique can achieve reliable high data rate transmission over a broadband wireless channel. A main challenge in wireless communication is retrieval of the channel state information and ICI cancellation. The channel estimation and ICI cancellation is estimated with the help of Iterative turbo channel estimation, Iterative pilot assisted channel estimation and ICI Cancellation techniques.
Keywords: (MIMO), (OFDM), ICI.
