%A Such, Gereon %A Schraml, Matthias %A Knopp, Andreas %D 2018 %T Frequency Domain Channelizer: A computationally efficient method for non-uniform channelization %K %X We present both, generalized theory and our implementation of a frequency domain channelizer suited for multicarrier Software Defined Radio receivers. Frequency domain channelizers fill the gap between multiple FFT/FIR-based channelizers and the polyphase channelizer considering dissimilar bandwidth carriers in a signal in terms of performance and applicability. Our open source implementation gr-FDC outperforms a combination of Frequency Xlating FFT filters at about ten channels and is introduced as an implementation example. %U https://pubs.gnuradio.org/index.php/grcon/article/view/51 %J Proceedings of the GNU Radio Conference %0 Journal Article %V 3 %N 1 %8 2018-09-18
