Multiplier-Free Bandpass Filter-Based Channelizer
Siwoo Noh, Oh-Bong Kwon, Fred J. Taylor · 2006
A new technique for implementing channelizers, based on multiplier-free bandpass filters is presented. The technical foundation for the new channelizer is found in the number theoretic properties of ternary valued polynomials and conventional cascaded integrator-comb (CIC) filters. The proposed channelizer possesses many of the attributes of the traditional CIC-based channelizer, plus others which are unique. The result is a new class of robust low-complexity channelizers.
