Patent ID: 7450634

Claim:
An equalizer arranged and constructed to mitigate adverse effects of a wireless channel, the equalizer comprising: a delay line, receiving an input signal and comprising a delay circuit coupled to an output combiner, the delay line operable to provide an interim signal; a feed forward circuit coupled to the delay line and operable to provide a feed forward signal that comprises a hard decision scaled according to a scaling factor corresponding to an estimate of channel parameters; and a feedback circuit coupled to the delay line and operable to provide a feedback signal that is scaled according to an other sealing factor corresponding to the estimate of the channel parameters and wherein the delay line further comprises an input combiner operable to combine the feedback signal and the input signal to provide a signal at an input to the delay circuit, wherein the output combiner is operable to combine the feed forward signal and the interim signal to provide an output signal that is delayed relative to the input signal and compensated for an adverse effect of the wireless channel on the input signal.
