Abstract

This paper proposes a new FIR fillet architecture for the spectral shaping filter used in the transmitter and the receiver for QAM-VDSL modem. This architecture reduced the hardware property and the power consumption. We derive algorithms for reducing the number of multipliers and the memory architecture for reducing the power consumption. The proposed filter has been implemented using VHDL and performed functional simulation.
