A MIMO SM-NSTBC Scheme for High Altitude Platform Communication Systems: Study and Analysis

Abstract

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.
