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...
This paper presents reduced signal decoding complexity 8×8 and 16×16 MIMO V-BLAST systems. The reduction in complexity is achieved by implementing a method that lowers the total the number of iterations needed in the decoding of the V-BLAST signals. Results show that the scheme is able to provide up to 71.06% signal decoding time reduction with minimal symbol-error-rate performance degradation. However,...
