英文摘要： In order to break through the limitation of the existing wireless communication theory, technology and system for underground coal mine, various kinds of resources such as space, time and frequency will be utilized effectively and comprehensively. In this way, we hope that the wireless overlay performance, capacity and data rate of wireless communication system for underground coal mine can be improved significantly. A cross-layer adaptive wireless transmission for Space-Time Coded Cooperation in MC-CDMA for underground coal mine will set up based on the channel condition and tunnel structure of underground coal mine. In the methods of cross-layer design, the combined Space-Time Coding and channel coding, multi-user collaboration mechanism as well as the signal transmission, channel estimation, signal detection theory and algorithm and the radio resource management technology which will adapt underground environment and user requirement, will be studied. The wireless signal transmission, estimation and detection theory and technology as well as the corresponding patents of the proposed scheme will be acquired. The baseband hardware prototype system will be developed to verify scheme and key technology proposed. It will provide the theory foundation and technology support for future optimization design of wireles
