Structured Dispersion Matrices From Division Algebra Codes for Space-Time Shift Keying [PDF]
, 2013 We propose a novel method of constructing Dispersion Matrices (DM) for Coherent Space-Time Shift Keying (CSTSK) relying on arbitrary PSK signal sets by exploiting codes from division algebras. We show that classic codes from Cyclic Division Algebras (CDA)
