The filter bank multicarrier (FBMC) transmission technique leads to an enhanced physical layer for conventional communication networks and it is an enabling technology for the new concepts and, particularly, cognitive radio.

The objective of this document is to provide an overview of FBMC, with emphasis on the features which impact communication networks. The only prerequisite for reading the document is basic knowledge in digital signal processing, in particular sampling theory, fast Fourier transform (FFT) and finite impulse response (FIR) filtering. More thorough developments on the techniques described, as well as alternative and more sophisticated methods, are available on the website http://www. ict-phydyas. org.
