An Oversampled Modulated Filter Bank Based Transmultiplexer With Precoding and Equalisation

This paper addresses an oversampled filter bank transmultiplexer applied to a power line communications scenario. The authors proposed structure has a low oversampling ratio and therefore introduces only a small amount of redundancy. Of particular interest are the possibility to iterate the filter bank in order to shorten the overall response, which is traded-off against the use of precoding or equalisation in order to target remaining ISI is only a low number of multiplexed bands are used. However, they demonstrate the iteration of the filter banks does not reduce the problem of timing synchronisation.
