Receiver circuit having adaptive equalizer with characteristics determined by signal envelope measurement and method therefor

摘要

Circuitry, and an associated method, for a receiver which receives data signals transmitted upon a non-ideal transmission channel. The circuitry includes an equalizer circuit and a variable gain amplifier circuit together operable to counteract the effects of the signal degradation. Characteristics of the equalizer circuit and of the amplifier circuit are together selected responsive to detection of the signal envelope of the data signal.
