Research And Verification On Implementation Schemes Of Measurement-based Parallel MIMO Channel Sounder

In recent years,the technology of mobile communication develops rapidly.The mobile communication is easy to connect and used widely now,so the information exchange is not only from person to person but from person to object or from thing to thing.We all can see,it has made changes the way we live,generally.So it appears many new scenarios in mobile communication,and we need to do some research about these new channel scenarios.We also need a new channel sounder to sounding the channel measurements,which is more advanced and more accurate.The 5G as the next technology of communication is added in many new application scenarios,including open space in gathering,metro,stadium,office area,highway,intensive residential area and wide coverage area.To use a better channel sounder measuring new channel scenarios is very important to improve the better communication service.In this thesis,the implementation scheme of parallel MIMO channel sounder will be used to study and the verification scheme base on measurements of it will be done.The research work of the thesis is as follow:Firstly,this thesis will do some research work about some international companies which can provide the MIMO channel sounder,and compare with the principle of realization of all the MIMO channel sounder and summarize function and performance requirement of parallel MIMO channel sounder which can support more channel measurements of different channel scenarios according the investigation.Secondly,that the key technical Schemes research to use in the parallel MIMO channel sounder is as an innovation point in this thesis.By applying the key technical Schemes in the parallel MIMO channel sounder,the precision of calibration,synchronization and trigger is improved significantly.Then the implementation scheme of parallel MIMO channel sounder will be used to study in the aspects of hardware platform and software platform in this thesis.At last,the platform for verifying the function and performance requirement of parallel MIMO channel sounder will be set,and will be used to do the verification for all the function and performance requirement of parallel MIMO channel sounder.Finally,the parallel MIMO channel sounder will turn out to be effective base on an actual channel scenario in May 2016.The channel measurement project is implemented.By using this channel sounder to get the information of the channel and using channel parameters extraction algorithm to get the channel parameter,the work of channel parameter analysis and channel modeling.At last,the large-scale fading path loss model and log-normal distribution shadowing will be proposed,and determining the scatter position in the real scenario by using the results of multi-path is proved the measurement channel data effectively to a certain extent.These are the work and innovation of the thesis,we hope they can be referential to the MIMO channel sounder and channel measurement.And then,we hope they can be used to measure new channel scenarios and improve the standardization of channel measurement.
