In this paper, we propose a novel class of unitary space-time constellations based on quaternary quasi-orthogonal sequences (QOSs), minimizing the maximum correlation between the s...
Abstract—In this treatise we propose a three-stage twin-transmitantenna assisted MultiUser (MU) Direct Sequence Code-Division Mulitple Access (DS-CDMA) system employing both a Un...
