Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: It has been shown recently that the maximum rate of a 2-real-symbol (single-complex-symbol) maximum likelihood (ML) decodable, square space-time block codes (STBCs) with unitary ight matrices is 2a over 2 a  complex symbols per channel use (cspcu) for 2 a  number of transmit antennas [1]. These STBCs are obtained from Unitary ight Designs (UWDs). ,  show that the maximum rates for 3- and 4-real-symbol (2-complex-symbol) ML decodable square STBCs from UWDs, for 2 a  transmit antennas, are 3(a−1) over 2 a  and 4(a−1) over 2 a  cspcu, respectively. STBCs achieving this maximum rate are constructed. A set of sufficient conditions on the signal set, required for these codes to achieve full-diversity are derived along with expressions for their coding gain.
