Enforcing energy balance in coherently superimposed optical vortices
Jaime Cisternas, Jaime A. Anguita, Gustavo Funes
The generation of optical beams with multiple, mutually-coherent orbital-angular-momentum (OAM) modes using phase gratings is analyzed from the perspective of energy distribution a…

Bethe Free Energy Approach to LDPC Decoding on Memory Channels
Jaime A. Anguita, Michael Chertkov, Mark A. Neifeld +1
We address the problem of the joint sequence detection in partial-response (PR) channels and decoding of low-density parity-check (LDPC) codes. We model the PR channel and the LDPC…
