Abstract
Embodiments include a method comprising: receiving a signal comprising a plurality of symbols; estimating that a first symbol of the plurality of symbols has a first value; based on the first value of the first symbol, cancelling, at least in part, inter symbol interference that the first symbol has on a second symbol of the plurality of symbols; determining a first error associated with the first value of the first symbol; and in response to the first error being higher than a threshold value, generating, for the first symbol, a second value that is different from the first value of the first symbol, and based on the second value of the first symbol, cancelling, at least in part, inter symbol interference that the first symbol has on the second symbol.
