Study on Grassmannian Constellation Based on Antipodal Points and Orthogonal Design and Its Simplified Detecting Algorithm

Based on antipodal points on a Grassmannian manifold, this paper proposes a framework for the unitary space time modulation (USTM) constellation. The antipodal constellation allows for a more straightforward ML detection approach. The algebraic orthogonal USTM constellation is an antipodal constellation that, in addition to being adaptable to the antipodal simplified ML detector, also has…
