英文摘要： Signal attenuation caused by the environmental conditions of the curved branch of the underground mine tunnel, loss media will greatly reduce the performance of the wireless transmission. Cooperative communication technology can expand the antennas of the other nodes to effectively improve gain and spatial diversity of wireless transmission, keeping the advantages of multi-hop and multiple antenna. It can overcome the bottleneck problem of wireless communications for mine safety in production and post-disaster rescue. Considering the application requirements on integrated transmission of various types of business information flow, this project focuses on the multi-stream multi-objective optimization transmission problems based on cooperative communication by constructing virtual MIMO (multiple inputs and multiple outputs) cooperative transmission model among nodes according to the concept of information flow. It will meet the transmission requirements of quality of service for the underground multiple types of business information flow. This research includes analysis and model of transmission characteristic, audio flow cooperative transmission with tradeoff between delay and bandwidth, video flow cooperative transmission and schedule with rate optimization, real-time cooperative transmission of scalar quantity
