    A MIMO SM-NSTBC Scheme for High Altitude Platform Communication Systems: Study and Analysis
    (Institute of Electrical and Electronics Engineers Inc., 2019) Shrutkirthi, G.S.; G.D., S.G.D.; Shripathi Acharya, U.S.
    In this paper, the performance of a novel non-binary Spatially Modulated Non-orthogonal Space Time Block Code (SM-NSTBC) scheme for High Altitude Platform (HAP) communication systems is designed and analyzed. SM-NSTBC utilizes full rank length n cyclic codewords derived over Galois Field (GF(q{m})), where (nvert q{m}-1 and m < n). In order to obtain higher spectral efficiencies in terms of data rate, NSTBC schemes have been devised. SM-NSTBC gives an improvement in the BER performance of ∼ 3 dB as compared to other conventional STBC-SM schemes given in literature. Monte Carlo simulations have been performed to validate the results. The computational complexity of the proposed scheme has been analytically derived and estimated. © 2019 IEEE.
