A receiver for receiving a signal transmitted through a transmission channel includes an equalizer and a first quality calculator that obtains a first quality value of the received signal. The equalizer includes a first channel estimation unit that estimates a first channel response of the transmission channel from the received signal using a first estimation scheme, and a second channel estimation unit that estimates a second channel response of the transmission channel from the received signal using the second estimation scheme. The equalizer equalizes the received signal using the first or second channel response and outputs the equalized signal. A portion of the second channel estimation unit halts depending on the first quality value.
