Abstract

A hybrid equalisation concept for a single carrier very high bit rate twisted pair downstream (26 Mbit/s) receiver is proposed. The equaliser´s requirements and performance are investigated and a technique aiming to combat radio frequency interference (RFI) digitally is proposed. The proposed method employs an adaptive notch filter to trace and reduce the RFI levels and-consequently-reduce the equaliser implementation complexity. Simulation results illustrate the desirable characteristics of the proposed scheme and confirm its ability to efficiently cope with narrowband interference
