<p>Provided are a transmission line estimation device, a transmission line estimation method, and a receiver in which desired performance is obtained even when the known signal series length is equal to a tap length or shorter than a tap length. The transmission line estimation device generates an estimated reception signal from a tap coefficient and a known signal series stored in the transversal filter unit (2), generates an error signal from the difference between the reception signal and the estimated reception signal, generates a known signal series, a tap coefficient, and a tap coefficient updated from the error signal, designates an effective interval formed from a predetermined number of taps in a plurality of taps in the transversal filter unit (2), and designates a first interval and a second interval set so as to include the center tap. The generation of the estimated reception signal and the generation of the updated tap coefficient are performed by generating an estimated reception signal and updated tap coefficient for the first interval, and by generating an estimated reception signal and an updated tap coefficient for the second interval.</p> |
