Lattice-reduction-aided equalisation for transmission over intersymbol-interference channels

摘要

Transmission over channels that produce intersymbol interference is considered. New equalisation schemes derived from recently proposed lattice-reduction-aided equalisation of multiple-input/multiple-output channels are presented. The schemes exhibit low complexity, require no or only very little channel state information at the transmitter, and channel coding can be immediately applied. The connection to partial-response signalling and state-of-the-art equalisation schemes is explained. Numerical simulations show good performance of the equalisation scheme.
