Claim 7:
8. A decoherence processing system, applied to a coherent light receiving device, wherein the coherent light receiving device comprises a plurality of photoelectric conversion units, and wherein the system comprises: N phase difference detection modules, N phase compensation modules respectively corresponding to the N phase difference detection modules, and a signal superposition and output module, wherein N is an integer greater than 1, wherein
each of the photoelectric conversion units is configured to receive a light signal and converted the light signal into an electrical signal;
each of the phase difference detection modules is configured to compare an electrical signal converted by a photoelectric conversion unit connected to the phase difference detection module with a reference signal to obtain a phase difference;
each of the phase compensation modules is configured to compensate the electrical signal converted by the photoelectric conversion unit connected to the phase compensation module according to the phase difference; and
the signal superposition and output module is configured to superimpose electrical signals comprising N compensated electrical signals and output an electrical signal obtained by the superposition.
