Abstract:
A method of receiving repeated transmissions of a same multilevel signal, comprising the steps of:a) storing amplitude values of said multilevel signal of a plurality of repeated transmissions in locations of a memory respectively corresponding to the transmissions;b) reading a set of amplitude values simultaneously from said locations of the memory and comparing the set of amplitude values with a plurality of mutually separated decision threshold bands respectively representing data symbols; andc) making a decision in favor of the data symbol of a decision threshold band if a majority of the set of amplitude values lie within the decision threshold band, or in favor of the data symbol of a decision threshold band if only one amplitude value of the set of amplitude values lies within or nearest to the decision threshold band and other amplitude values of the set are not nearer to any of said plurality of mutually separated decision threshold bands than said only one amplitude value is near to the decision threshold band.
