Abstract

This paper investigates the use of effective and flexible fast-convolution (FC) implementation for two main types of filter bank multicarrier (FBMC) waveforms, FBMC/OQAM and filtered multitone (FMT). The generated waveforms are spectrally well-contained, with very small power leakage to adjacent frequencies, and are thus good candidates for opportunistic and heterogeneous spectrum use scenarios. On the receiver side, the FC filter bank (FC-FB) approach can be used for simultaneously processing multiple channels with individually tunable bandwidths, center frequencies, and timing offsets, supporting asynchronous multi-user operation. FC-FB implementations are compared with traditional polyphase designs in terms of spectral characteristics and computational complexity.
