TY - JOUR AU - Such, Gereon AU - Schraml, Matthias AU - Knopp, Andreas PY - 2018/09/18 TI - Frequency Domain Channelizer: A computationally efficient method for non-uniform channelization JF - Proceedings of the GNU Radio Conference; Vol 3 No 1 (2018): Proceedings of the 8th GNU Radio Conference KW - N2 - 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.
