摘要：In one embodiment of the communications network the predeterminedencoding scheme and symbol constellation configurations are chosen so that the rangein channel qualities that the encoding scheme and symbol constellation configurations
are designed to be utilized within overlap with each other. This overlapping provideshysteresis, which reduces the frequency with which a subscriber must alter encodingscheme and symbol constellations. Reducing the frequency of changing encoding schemeand/or symbol constellation eliminates the communication overhead associated withthese changes and increases throughput by enabling the subscriber to spend more timetransmitting data.
