In this paper, we investigate detectors for transmultiplexer-based high bit rate transmission over dispersive channels like telephone wires. The transmitter is based on a synthesis stage. At the receiver we design, for an MMSE criterion, fractionally spaced multiple-input/multiple-output (MIMO) linear detectors applied after an analysis stage. The receiver may be upgraded with a MIMO decision-feedback (DF) section. The performance of the system is investigated for filter banks and a twisted pair channel. The influence of the forward section rate is investigated. The potential of these detectors is clearly demonstrated. Besides, reduced complexity solutions are also put forward.
