Abstract: An apparatus for estimating channel effects is provided. A receiving module receives first data and first reference information arriving in a first time period, second data and second reference data arriving in a second time period, and third data and third reference data arriving in a third time period. An estimation module estimates channel effects corresponding to the first and third data, and the first, second and third reference data, respectively. A coefficient calculation module performs a Wiener filter coefficient calculation on the channel effects corresponding to the first, second and third reference data to generate a set of time-domain interpolation coefficients. An interpolation module interpolates the channel effects corresponding to the first third data according to the set of time-domain interpolation coefficients to generate a channel effect corresponding to the second data.
