Abstract:
Provided are a transmission channel estimating device, a transmission channel estimating method, and a receiving apparatus. A transversal filter unit generates an estimated reception signal on the basis of a stored known signal sequence and tap coefficients, generates an error signal on the basis of a difference between a reception signal and the estimated reception signal, generates updated tap coefficients on the basis of the known signal sequence, the tap coefficients and the error signal, designates an effective section formed by a predetermined number of taps out of a plurality of taps in the transversal filter unit 2, and designates a first section and a second section set so as to include a center tap, wherein the generation of the estimated reception signal and the updated tap coefficients is performed by generating an estimated reception signal and updated tap coefficients for the first section and generating an estimated reception signal and updated tap coefficients for the second section.
