Phase Diversity Method in Mobile Communication Systems
Phase diversity techniques are used in many communication systems, including PAL TV system, FBS method, and the Alamouty algorithm for MIMO. Phase diversity algorithms have proved effective in mitigating phase distortion in wireless channels. In this paper the authors present a new method of phase diversity processing that is based on phase arithmetical summing. The Diversity is a well-known technique for improving the performance and reliability of wireless communications over fading channels. In this approach, signals are transmitted through multiple channels, each having an independent fading, and coherently combine them at the receiver. Different types of diversity (frequency, time, space, phase) are widely used today in modern communication systems.
