  • Abstract
    A report is made on one of the issues first observed when using a block-floating-point system in a time equaliser of an ADSL modem. It is believed that, until now, this important phenomenon has been neglected by researchers. It is shown that neglecting this issue may increase the round-off error significantly. Two solutions to improve performance are proposed.
