Abstract
A method and system for efficient dual polarity transmission of a millimeter wave data stream of overall rate Rfixed+Rvar+RMAC through two channels of polarities H and V. The method comprises the steps of determining asymmetric H and V transmission powers such that the overall rate Rfixed+Rvar+RMAC is maximized, determining asymmetric ηH and ηV spectral efficiencies according to the asymmetric H and V transmission powers, and determining asymmetric coding and interleaving parameters related to the asymmetric ηH and ηV spectral efficiencies.
