Abstract


Short-wave communication plays an important role in military communications , but by the impact of poor HF channel stability , its system capacity is smaller and less reliable . As the latest application of MIMO technology - Collaborative communication can be an effective solution to this problem , by multiple users to collaboratively build virtual MIMO channel to achieve transmit diversity in mobile terminal , to improve the transmission quality of the wireless communication system uplink . In order to improve the effect of short-wave communication transmission , a natural idea is the introduction of cooperative communication shortwave network . This paper focuses on collaborative communication in the the shortwave set of network communications applications related research . The knowledge of shortwave communication network . Second, start from the traditional diversity , collaboration communication concepts, principles , focusing on analysis of the Alamouti space-time block code and its collaborative communication . Then, the introduction of cooperative communication shortwave networking , build a based shortwave collaboration collaborative communication model , and the uplink capacity and performance analysis and simulation . The results show that the shortwave collaboration can improve the capacity of the short-wave communication system , and further reduce the error rate of the system . Finally , the full text summarizes the prospect of the future research directions .
