Abstract

Oversampled filter banks have recently been considered for channel coding applications as well as precoders and equaliser, whereby both inter-symbol interference and channel noise can be mitigated by the filter bank design. Existing methods are block-based designs which dedicate degrees of freedom towards cancelling inter-block interference. In this paper, we propose a non-block based OSFB design for precoding and equalisation, which is based on Mertins' extended Wiener solution, whereby polynomial matrices are admitted for precoders and equalisers by applying a recently proposed broadband eigenvalue decomposition (BEVD) algorithm. Some simulation results are provided to highlight the effectiveness of the proposed approach.
