Abstract: Various embodiments relate to a method and circuit for combining channels, the method including receiving, by a matching and smoothing filter, a signal from an analog to digital converter and extracting a root mean square signal level, receiving, by a noise power detector (“NPD”), the signal from the ADC and assessing noise contribution on the signal and receiving, by a maximum ratio combiner, the signal from the matching and smoothing filter wherein a combiner selects between using a geometric sum and an arithmetic sum to combine the channels.
