Abstract :
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
