ADAPTIVE EQUALIZER, ADAPTIVE EQUALIZATION METHOD AND RECEIVER

摘要

An adaptive equalizer, an adaptive equalization method and receiver are disclosed where the adaptive equalizer is used for performing adaptive equalization processing on a frequency-domain signal, a channel used by the frequency-domain signal containing multiple subcarriers, the adaptive equalizer comprises: an equalizer coefficient generating unit configured to, for each subcarrier, generate an equalizer coefficient to which the subcarrier corresponds according to channel information and a step length of the subcarrier; where different subcarriers correspond to different step lengths and an equalization processing unit configured to, for each subcarrier, perform equalization processing on a signal in the subcarrier by using the equalizer coefficient.
