Sparse Grassmannian Design for Noncoherent Codes via Schubert Cell Decomposition
IEEE Open Journal of the Communications SocietyIn this paper, we propose a method for designing sparse Grassmannian codes for noncoherent multiple-input multiple-output systems. Conventional pairwise error probability formulations under uncorrelated Rayleigh fading channels fail to account for rank ...
