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.}, url = {https://pubs.gnuradio.org/index.php/grcon/article/view/51} }
