The minimum intersymbol interference (min-ISI) method yields
time-domain equalizer (TEQ) designs for discrete multitone (DMT)
modulation transceivers that are close to channel capacity.
For eight standard ADSL channels, the min-ISI design method
reaches within 1% of the matched filter bound at the TEQ output.
However, the min-ISI method relies several computationally expensive
In this paper, we develop low-complexity algorithms for these
multiplications to allow for real-time implementation of the
min-ISI method on programmable digital signal processors.
