Success Ratio of Inter-Terminal Communications in Higher-Frequency Bands for Terminals Collaborated MIMO Reception

摘要

Currently, terminals collaborated reception, a type of MIMO (Multiple-Input Multiple-Output) communication using several terminals to receive the signal from a base station and to share their received signals with neighbors ana processing the signals. Because the conventional MU-MIMO needs to feedback the information of the channel matrix from the terminal to the base station, it is not suitable for use in public transport such as bus and train. The performance of terminal collaborated reception depends on not only channel state between the base station and terminals but also the performance of inter-terminal communication and spatial correlation between terminals. This paper focused on the cooperation success ratio between the collaborated terminals, autocorrelation were obtained at each receiving terminal in the vehicle and investigated the effects of various factors on it.
