Roll-off shaping filter design for improving adaptive equalisation
Abstract
Special choice of the group-delay characteristic of the roll-off shaping filter in the high-speed data-modem transmitter is suggested. It can make the task of the linear receiving equalizer easier by partial reduction in intersymbol interference caused by the transmission channel.
