适应于矿井无线传输的认知无线电技术

In order to ensure safe production, a variety of coal mine equipment and its surrounding environment should be controlled, which is based on web, but the expansion and liquidity of Ethernet, which uses fiber as its data transmission media, is much more restricted. With the development of wireless communication technology, what kind of wireless communication technology can be applied to coal mine environment have become more and more attention. Since the cognitive radio technology is a new intelligent wireless communications technology, it can be perceived environmental characteristics of the radio transmission, this paper analyzes the characteristics of the mine tunnel, as well as its requirement for the wireless communications network. This paper also describes the features of Ad hoc network topology and analysis the advantage of using cognitive radio technology which is based on the Ad hoc network topology in mine. Finally it summed up the study of key issues and future research directions.
