Abstract
In an Asymmetric Digital Subscriber Loop (ADSL) Discrete Multi-Tone (DMT) system, ADSL DMT equipment includes a decoder that operates on a received DMT signal representing Nf symbols/second, where N>1, to recover f symbols per second. In particular, the decoder decides each symbol value of the recovered signal as a function of values of a respective 2N symbol values from the received DMT signal.
