Abstract:
A method includes determining one or more metrics indicative of at least one of (i) interference on a communication link, (ii) noise on the communication link, and (iii) performance of a receiver receiving packets via the communication link, selecting a modulation and coding scheme as a function of (i) the determined one or more metrics, and (ii) one or more Quality of Service requirements for the communication link, and correcting the selected modulation and coding scheme using a current value of a correction factor. The corrected modulation and coding scheme is to be used to generate one or more packets. The method also includes determining an error rate corresponding to packets previously transmitted over the communication link, and adjusting the correction factor based on the determined error rate. Adjusting the correction factor includes incrementing or decrementing the correction factor.
