Contiguous channel bonding for using more than one channels together in TV white space has been considered in the IEEE 802.22-specified wireless regional area network system. To support more flexible channel usage, this paper investigates non-contiguous channel bonding as a potential extended feature of IEEE 802.22 standard. The transceiver structure with Non-Contiguous OFDM (NC-OFDM) transmission to support non-contiguous channel bonding is presented. The simulation results show that non-contiguous channel bonding achieves better symbol error rate performance with slightly higher peak to average power ratio comparing with contiguous channel bonding. Finally, the power spectrum density of NC-OFDM signals with non-contiguous channel bonding is analyzed and the number of additional guard subcarriers for mitigating out-of-band emissions are determined to comply with the required transmission spectrum mask.
