Abstract: There exist several methods for mitigating the impact of channel conditions on signal integrity. These methods increase both the transmitting power and redundancy. In this paper we review the known Phase Diversity method proposed by Walter Bruch for mitigating phase distortions in the PAL TV systems, and discuss its applications in modern wireless communications such as MIMO systems based on the Alamouti algorithm. We’ll present the implementation of this method in FBS systems, which allow for elimination of Doppler Effects on OFDMA signals without pilot signals.
