Abstract

See full text

An apparatus includes an optical communications receiver receiving a turbulence-distorted, optical signal. The turbulence-distorted, optical signal includes a plurality of fundamental modes encoded via a combinatorial multiplexings dictionary. The received optical signal includes a plurality of two-dimensional images. Each two-dimensional image of the plurality of two-dimensional images respectively represents received fundamental modes of the plurality of fundamental modes. The receiver includes a neural network trained to assign to each two-dimensional image of the plurality of two-dimensional images at least one respective active fundamental mode of the plurality of fundamental modes and a corresponding accuracy probability based on the dictionary.
