Abstract:Due to small sideband power leakage, filter bank
multicarrier techniques are considered as interesting alternatives
to traditional OFDMs for spectrum pooling Cognitive Radio.
In this paper, we propose an oversampled filter bank multicarrier
system for Cognitive Radio. The increased spacing
between adjacent subcarriers in the oversampled filter bank
multicarrier system largely reduce the intercarrier interference,
the key limitation of the OFDM based Cognitive Radio. The
proposed multicarrier system is compared with OFDM for BER
performance and sideband power rejection. Design tradeoffs of
the major parameters of the oversampled filter bank will be
discussed. We also suggest a fast implementation of the proposed
filter bank modulation based on generalized DFT filter bank
model, followed by a computational complexity analysis.
