A Differential Detection Scheme for MIMO Systems with Phase Rotation
Sun Defu · Telecommunication Engineering · 2011
A differential detection scheme is proposed which is based on Alamouti's transmission scheme,and the proposed scheme can provide higher spectrum efficiency with phase rotation.The simulation results show that the proposed scheme increases the spectrum efficiency because of the angle information.On the other hand,the idea of angle rotation in this scheme can potentially be used in other differential detection scheme.
