Currently, detailed study of Orthogonal Space-Time Block Codes (OSTBC) in MIMO literature is mostly limited to conventional MIMO, i.e. MIMO systems with at most 8 transmit and 8 receive antennas. In view of the situation, this paper studies the implementation of OSTBC in Large MIMO systems. The paper presents OSTBC for transmission of real symbols that can support up to 32 transmit and 32 receive...
