In this paper, we investigate improved detectors for transmultiplexer-based high bit rate transmission over dispersive channels like telephone wires, The transmitter is based on a synthesis stage. For the receiver, we design fractionally spaced single-input/multiple-output linear detectors, possibly upgraded with a multiple-input/multiple-output decision-feedback section, For an MMSE criterion. The performance of the system is investigated For filter banks, classical DMT, and different channels. The potential of these detectors is demonstrated.
