Study on Grassmannian Constellation Based on Antipodal Points and Orthogonal Design and Its Simplified Detecting Algorithm | Chapter 5 | Theory and Practice of Mathematics and Computer Science Vol. 10

 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 a second simplified ML detector based on its self-indexing properties, which is simpler due to the elimination of the matrix operation. Under the provided framework, a searching orthogonal USTM constellation based on the grid search method is produced, and its minimal Frobenius chordal distance and simulation performance outperform the algebraic orthogonal USTM constellation.
