Methods and system for hopset selection

Abstract

A communication method includes obtaining power data associated with a plurality of channels of a frequency band and determining a counter of a set of signal-to-noise ratios (SNRs) for each of the plurality of channels. The set of SNRs is calculated based at least in part on power data for the each of the plurality of channels. The method further includes predicting an error rate for each of the plurality of channels based at least in part on the counter and selecting a hopset of channels for frequency hopping from the plurality of channels based at least in part on the predicted error rates for the plurality of channels.
