An efficient FPGA implementation of a pulse-shaping IIR filter
Naim Batani, Claude Thibeault, Christian S. Gargour · 2002
An efficient field programmable gate array (FPGA) implementation of an IIR pulse-shaping filter is presented. Several techniques have been used in order to decrease the filter's processing time and the coefficients quantization effects. The filter was designed to functionally replace as closely as possible an analog one used in a medium capacity digital microwave radio. Simulation and experimental results agree closely with the theoretical predictions.
