An illustrated embodiment disclosed herein is a method including correlating, by an endpoint, a first frame and a second frame with a plurality of hypotheses, detecting, by the endpoint, for each correlation of the first frame, a first metric and, for each correlation of the second frame, a second metric, identifying, by the endpoint, a first subset of hypotheses based on the first metric and a second subset of hypotheses based on the second metric, identifying, by the endpoint, pairs of hypotheses, each pair including a first hypothesis from the first subset and a second hypothesis from the second subset. The first hypothesis is same or within a predetermined distance of the second hypothesis. The method includes selecting, by the endpoint and from the pairs of hypotheses, a hypothesis based on the second metric and selecting, by the endpoint, a channel for transmission at which the hypothesis is selected.
