Multi-dimensional and non-uniform constellation optimization via the special orthogonal group
Multi-dimensional and non-uniform constellation optimization via the special orthogonal group
With the goal of optimizing the CM (coded modulation) capacity of a finite constellation over a Rayleigh fading channel, we use one-parameter subgroups of the Lie group of rotation matrices to construct families of rotation matrices which optimize a certain objective function controlling the CM capacity. Our construction does not …
