Research On The Technique Of MIMO In The Meteor Burst Communication

Meteor Burst Communication (MBC), a BLOS wireless communication which using meteor high-speed through atmosphere (the 80-120km upper air) to cause the ionization trail when friction burning, to reflect and scatter to the VHF radio wave and realize the remote communication. For its intermittent and burst characteristic, MBC' communication capacity is small and with a bad real-time performance. This article mainly analysis and research how to suitable introduce multi-antenna technology with space-time processing technology into point to point Meteor Burst Communication, that is multi-input and multi-output(MIMO) communication technology. Uses multi-path effects as a favorable factor, to resist the influence of the Meteor Burst Communication channel decline and improve the communication capacity of the Meteor Burst Communication (MBC), and to improve communication quality and enhance the system performance.In this article, firstly study foundation knowledge of Meteor Burst Communication (MBC), to clearly know that the advantage and disadvantage of the Meteor Burst Communication; Then, carefully analysis multi-antenna (MIMO) technology and made in-depth research space-time coding technology to realize multi-antenna technology performance; Finally, construct the Matlab simulation environment of Meteor trail Communication which using the MIMO technology, and obtain the performance technical data to analysis. The result of analysis is that multi-antenna technology can be possible method to improve the communication performance of the Meteor Burst Communication.
