Imperfect channel estimation results in the introduction of symbols coupling for system with space time codes encoding when decoded by the mismatched filter. The bootstrap algorithm was suggested to be used as a signal separator at the output of the mismatched filter. In this work, this solution is studied in details for the Alamouti's code. An inherent problem of the bootstrap's weights control process...
A novel distributed scheme that combines cooperative ARQ with the spectrum leasing paradigm is proposed and analyzed. The strategy harnesses the opportunistic gains of cooperative communications, while inherently providing a spectrum-rewarding incentive for the otherwise non-cooperative relays to assist the source's transmission. As in cooperative ARQ, the source might decide to hand over the possible...
