1. An equalization apparatus, comprising: a slave equalizer chain, which comprises a first decoder and a first adaptive filter comprising first coefficients, and which is configured to receive a first signal from a first antenna, to filter the first signal using the first adaptive filter to produce a first filtered signal, to decode the first filtered signal using the first decoder so as to generate a first output, and to adapt the first coefficients based at least on the first output; and a master equalizer chain, which comprises a second decoder and a second adaptive filter comprising second coefficients, and which is configured to receive a second signal from a second antenna, to filter the second signal using the second adaptive filter to produce a second filtered signal, to calculate using at least one weighting filter a weighted combination of the second filtered signal and the first filtered signal produced in the slave equalizer chain, to decode the weighted combination using the second decoder so as to generate a second output, and to adapt the second coefficients based at least on the second output.
