Abstract
A method is disclosed for frequency offset compensation and equalization in an orthogonal frequency division multiplexing system. The method comprises: acquiring a channel estimation value h and a frequency offset value f at a reference symbol; acquiring a Toeplitz matrix M(f) based on the frequency offset value f; performing phase compensation on the channel estimation value h to obtain a channel estimation value h' at a data symbol; and acquiring an estimation value of a transmitted symbol x based on M(f) and h′. A device is also disclosed for frequency offset compensation and equalization in the orthogonal frequency division multiplexing system. The device comprises a channel estimation unit, a frequency offset acquisition unit, a channel compensation unit and an equalization estimation unit.
