On the Prospect of Application of Space-Division Multiple-Access Technology to Coal Mine Communication
Abstract：Space-Division Multiple-Access technology (SDMA) is the embodiment of smart antenna technology. Taking advantage of the spatial difference of users, it uses antenna array to realize the commu- nication of multiple users in the same channel, and at the same time, the technology can expand the availa- ble resources of the communication system to the spatial domain. The SDMA technology can distinguish users by the different space propagation paths of signals, and is compatible with other Multi-access man- ner. Using this technology can greatly improve the function of the communication system. The wireless communication technology is a quite difficult study in coal mine fields. In the coal mine, the multipath fa- ding phenomenon is severe. The SDMA can effectively improve and reduce this multipath fading phenome- non. Its application in underground mines will bring huge breakthrough to the quality improvement of fu- ture underground mine communication.
