Assignee: CABLE TELEVISION LABORATORIES, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A receiver for processing an input signal from a communication network, comprising:
a processor; and
a memory configured to store computer executable instructions, which, when executed by the processor, cause the processor to:
receive an input data signal including digital bit information;
code the input data signal into a plurality of multi-level symbols;
map the plurality of multi-level symbols into a plurality of constellation points in the phase domain;
execute a first phase recovery subprocess on the plurality of constellation points to recover a first carrier phase of the input signal;
implement a Gaussian mixture model (GMM) algorithm on the recovered first carrier phase;
obtain, after implementation of the GMM algorithm, an enhanced recovered carrier phase; and
process the enhanced recovered carrier phase with a second phase recovery subprocess to reduce distortion from the input signal.
