Abstract

Filterbank multicarrier modulation (FBMC) has been identified as a strong contender for dynamic spectrum access in the TV White Space, as FBMC transceivers are able to control out-of-band interference level without compromising flexible usage. This paper compares FBMC receiver architectures, providing performance and complexity analysis, based on closed form expressions and on an actual implementation. Polyphase network (PPN-) and frequency spreading (FS-) FBMC receiver structures are discussed. The FS-FBMC structure is selected for hardware implementation and compared with OFDM. It is shown that complexity overhead is limited when hardware resource sharing techniques are exploited.
