Abstract:
1. A method for selecting, by a receiver, one of a plurality of candidate rates as a transmitted data rate, the method comprising: decoding, by the receiver, a received data frame using different candidate rates to generate a first decoded bit sequence associated with each candidate rate; generating, by the receiver, a first frame quality indicator and a first error metric for each of the candidate rates based on the associated first decoded bit sequence and a decoding metric for the associated first decoded bit sequence; filtering, by the receiver, the candidate rates based on the first error metrics and an error metric threshold to generate a first set of candidate rates including candidate rates having associated first error metrics passing the error metric threshold; and selecting, by the receiver, a candidate rate among the first set of candidate rates as the transmitted data rate based on at least the first frame quality indicators and, if the first set of candidate rates includes at least two candidate rates having acceptable frame qualities, the selecting further includes,
