Abstract

The design of FIR (finite-impulse response) partial response transmitter and receiver filter pairs for class I and IV is described. Each filter is designed to have equiripple stopband attenuation. For class I, the filters form a matched filter pair, while for class IV, the filters have nearly equal stopband attenuation. Moreover, the overall impulse response of each filter pair is approximated to produce minimum intersymbol interference. Two design examples are presented. One is a 57th-order class I filter pair having 0.05% ISI (intersymbol interference). The other is a class IV 61st-order transmitter and 57th-order receiver filter pair whose ISI is 0.2%.<>
