ABSTRACT:
Methods and systems provide for operating a modem receiver such as an ADSL modem receiver. As incoming data signals are received, a decoding scheme is selected from a plurality of decoding schemes based on a predetermined downstream data rate. In one approach a soft receiver architecture of an ADSL modem is able to select between relatively complex decoding schemes and relatively simple decoding schemes based on signal-to-noise ratio (SNR).
