The conventional frequency response masking (FRM) approach is one of the most well-known techniques for the design of sharp transition band finite impulse response (FIR) digital filters. The resulting FRM digital filters permit efficient hardware implementations due to an inherently large number of zero-valued multiplier coefficients. The hardware complexity of these digital filters can further be...
This paper presents a novel diversity controlled (DC) genetic algorithm (GA) for the optimization of frequency-response masking (FRM) FIR digital filters over the double base number system (DBNS) multiplier coefficient space. The use of DBNS multiplier coefficients reduces the complexity and power consumption in the hardware implementation of the resulting FRM FIR digital filters. A direct application...
Wireless sensor network (WSN) nodes require components with ultra-low power consumption, as they must operate without an external power supply. One technique for reducing consumption of a system is to scale it to a smaller technology; however, in recent technologies is not clear whether the decrease in dynamic power consumption outweighs the increase in static power consumption (due to leakage currents)...
