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 noncontiguous 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.

“…The digital modulation types used in this standard are QPSK, 16-QAM, and 64-QAM. OFDMA symbols are created using the 2048 FFT on 6, 7, and 8 MHz bandwidths which consist of 1440 data subcarriers, 240 pilot carriers, and 368 guards and DC subcarriers [6]. The cyclic prefix length can be 1/4, 1/8, 1/16, and 1/32 of OFDMA symbol duration.…”

“…This is equal to assert that in the simulation we have to consider 8 available possibilities, where each possibility is only constituted by one WRAN. The considered possibilities among which the coordinator can choose are (1),(2),(3),(4),(5)(6), (7), (8). The We run further simulations referred to the scenario in fig.1.…”

IEEE 802.22 is a standard for Wireless Regional Area Network (WRAN) which exploits the cognitive radio technology in order to use spectrum holes in the TV frequency band. The standard allows the sharing of unused spectrum allocated to the Television Broadcast Service without causing harmful interference to licensed users like TV transmitters and receivers. It is essential to perform an efficient channel assignment in cognitive 802.22 networks. In this paper we propose an original resource sharing algorithm which, working in a multichannel environment, aims at assigning channels to WRANs in such a way to satisfy their request and avoid completely the interference among them. It also takes into account the issue of spatial diversity, i.e. the case where some channels do not spatially cover all the WRANs. The effectiveness of the multichannel resource sharing scheme is proved through simulations, and in particular the number of assigned slots is evaluated. The results show that the algorithm makes a resource assignment which satisfies the requests avoiding interference among overlapping WRANs.
