Abstract:
1. A method, comprising the steps of: transmitting from a transmitter of a first transceiver a plurality of symbols over a communication channel that imparts inter-symbol interference to said symbols; receiving at a receiver of a second transceiver said symbols; determining a soft decision metric at the receiver of the second transceiver for the plurality of symbols; employing the soft decision metric at the receiver of the second transceiver to determine mean symbol error probability or mean bit error probability; transmitting from the second transceiver to the first transceiver a signal that carries said mean symbol error probability or mean bit error probability; comparing at the first transceiver the mean symbol error probability or the mean bit error probability to one or more predetermined thresholds to select a communication channel; wherein the first transceiver implements a first communication protocol for the communication channel upon the means symbol error probability or the mean bit error probability exceeding a first threshold of the one or more predetermined thresholds; wherein the first transceiver implements a second communication protocol for the communication channel upon the mean symbol error probability or the mean bit error probability exceeding a second threshold of the one or more predetermined thresholds.
