Abstract
A receiver unit includes a prefilter that receives as one of the inputs a channel impulse response (CIR) estimation data set and removes unnecessary data information from the CIR estimation data set and filters input signal so to form a first output data set. An equalizer core receives the first output data set and based on computed CIR length and SNR value of the first output data set so as to determine which portion of the first output data set are assigned to at least one of at least two low complexity equalization modules used for processing.
