Locally Diverse Constellations From the Special Orthogonal Group
Locally Diverse Constellations From the Special Orthogonal Group
To optimize rotated multidimensional constellations over a single-input single-output Rayleigh fading channel, a family of rotation matrices is constructed for all dimensions which are a power of 2. This family is a one-parameter subgroup of the group of rotation matrices, and is located using a gradient descent scheme on this …
