Effect of Carrier Frequency offset on Cooperative Alamouti STC OFDM Systems

In this paper, the effect of carrier frequency offset on a network where multiple independent devices cooperate to form virtual multiple input multiple output networks is analyzed. The common phase error and intercarrier interference effect on cooperative Alamouti STC OFDM system due to carrier frequency offset is investigated and OFDM based cooperative communication system for mitigating the effect of carrier frequency offset is developed.
