A Study of the Modeling of the VMIMO Channel Based on Cooperative Relay Technology

For the Limitations of MIMO systems in mobile terminal, this paper has provided an easily implemented virtual MIMO
（VMIMO）communication channel model based on cooperative relay technology, by using the geometric modeling method on the basis of scatterers' distribution. In Rican fading environment, the relevant statistical properties of the channel model are studied. And, the closed expressions of the correlation function are deduced. And the parameters of this channel model such as the antenna interval, the angular spread, the Doppler effect, and the mobility of the terminal, etc. are all considered, simulated and analyzed. The simulation results show that the VMIMO based on cooperative relay technology can take advantage of the superiority of MIMO technology to achieve higher performance.
