Abstract:
1. A communication receiver that is operable to receive a signal that is transmitted via communication channel, the received signal comprising a training sequence portion and a data portion, the communication receiver comprising: a channel estimation block that is operable to estimate a characteristic of a communication channel; and a channel equalizer block that is operable to calculate a plurality of channel equalizer tap coefficients, the plurality of channel equalizer tap coefficients being used to equalize for any communication channel-induced changes within the received signal; and wherein the channel estimation block and the channel equalizer block performs repeated adaptation; the channel estimation block being operable to employ repeated adaptation on the training sequence portion and the data portion, the repeated adaptation of the channel estimation block being performed using a plurality of channel estimation cycles; and the channel equalizer block being operable to employ repeated adaptation on the training sequence and the data portion, wherein the channel equalizer block calculates the plurality of equalizer tap coefficients by performing repeated adaptation on the training sequence portion and the data portion using the plurality of channel equalizer cycles; and wherein the plurality of channel estimation cycles includes a plurality of regions; and wherein the channel estimation block performs region-dependent error handling using repeated adaptation on the training sequence portion and the data portion.
