OFDM Versus Filter Bank Multicarrier (2011, background): “OFDM is thus a poor fit because the filters associated with its synthesized subcarrier signals (at the transmitter) and analyzed subcarrier signals (at the receiver) have relatively large side lobes and such lobes will result in leakage of signal powers among the bands of different users [7].”
Filter Bank Spectrum Sensing for Cognitive Radios (2008, background): “We are particularly interested in filter banks that may also be used for multicarrier communications in CR networks [5]–[7].”
OFDM Inspired Waveforms for 5G (2016, neutral): “spectrum sensing [16]–[21].”
A Survey on Multicarrier Communications: Prototype Filters, Lattice Structures, and Implementation Aspects (2012, methodology): “For example, [147] shows that the use of filter banks yields similar spectrum sensing accuracies when compared to those of optimum multi-taper based spectrum sensing method with less computational complexity.”
Signal Processing in Cognitive Radio (2009, methodology): “Recently, filter bank multicarrier communication techniques, including the OFDM-OQAM, CMT, and FMT, have been proposed as alternative physical-layer candidates of CR systems [16].”
