A proposed enhanced scheme for the dynamic frequency hopping performance in the IEEE 802.22 standard

This paper presents an integrated scheme for the dynamic-frequency-hopping DFH technique provided in literature for the IEEE 802.22 standard supporting wireless regional area networks WRANs. The performance of DFH is analyzed thoroughly for various channel models and for a multiple-input multiple-output systems. The core of this research is based on the coexistence of digital terrestrial TV broadcasting and the WRANs in the TV white space. The proposed technique aims at protecting the incumbent users from interfering with the cognitive broadband access in the TV spectrum. In order to achieve this, spectrum sensing is performed in the intended working channel in DFH while spectrum monitoring with an energy-ratio ER algorithm is applied during the WRAN data transmission in the working channel. Hence, in the DFH-ER algorithm, the reappearance of a digital terrestrial TV signal in a band occupied by the WRANs would be detected immediately. This will provide interference free performance for the licensed signal as well as reliable data transmission for the unlicensed ones. Both analyses and simulation results of the proposed DFH-ER technique compared with the conventional DFH scenario exemplify the enhancement of the WRAN data transmission while protecting the digital terrestrial TV users.
