ABSTRACT:
Methods of scaling path delay values in a communication system, in which estimates of received symbols corresponding to the path delays are combined, include the step of determining a respective weight value for each path delay based on relative correlations of the path delays. The weight values may be determined by getting a plurality of path delay values; identifying the path delay values as either peak values or neighbor values; organizing the peak values and neighbor values into groups, with each group including at least one peak value and at least one neighbor value; for each group, determining a set of weight values; and checking the groups for duplicated path delay values and selecting a weight value from the weight values determined for the duplicated path delay values as either one of the weight values for the duplicated path delay values or a combination of the weight values for the duplicated path delay values. Receivers in digital communication systems and computer-readable media are also disclosed.
