On the Performance of High Speed Wireless Access System with Dual-Hop MIMO Relays

In this paper, we have proposed link balancing scheme based on MIMO switching for the high speed wireless access system via dual-hop MIMO relays, and analyzed the capacity of different MIMO transmission mode. From these studies, we can conclude that the relayed MIMO system can support high speed group mobility and the link balancing method is able to enhance the transmission performance.
