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&#x2032;. 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.

Frequency offset compensation and equalization method and device in an orthogonal frequency division multiplexing system

The present invention discloses a method for determining a subband index, the method comprises: an Evolved Node B (eNB) receives r, calculates a difference between the received r and a formula corresponding to each obtained subband index, searches sequences in a stored intermediate value table according to the calculated difference to obtain each sconstituting {s}. The present invention further discloses a device for determining a subband index, the device comprises a table generation module, a receiving module and a calculation module. The method and device disclosed in the present invention are capable of reducing the storage space needed for a subband index report.
