Channel equalization method and apparatus, and receiver

A channel equalization apparatus, comprising:

• a channel transfer matrix acquiring module, configured to acquire a channel transfer matrix according to a training sequence sent by a transmit end;
• an amplitude response matrix acquiring module, configured to acquire an amplitude response matrix of the channel transfer matrix;
• a window determining module, configured to acquire, according to the amplitude response matrix, a window length of a sliding window that is required for performing noise filtering on the channel transfer matrix;
• and
• an equalization module, configured to perform noise filtering on the channel transfer matrix according to the window length of the sliding window, and perform, according to a channel transfer matrix that is obtained by means of noise filtering, channel equalization on a data payload sent by the transmit end.
