Distributed one bit feedback extended orthogonal space time coding based on selection of cyclic rotation for cooperative relay n
In this paper, a novel closed-loop distributed extended orthogonal space time block code (D-EO-STBC) with one-bit feedback based on selection of phase rotation is proposed for two...
