DECODING METHOD, RECEIVING DEVICE, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2022/068680

Kind Code:

A1

Abstract:

Disclosed in the embodiments of the present invention are a decoding method, a receiving device, and a storage medium, which are used to suppress inter-symbol interference by means of the correlation between at least two symbols adjacent to one another, thus avoiding the loss of effective information conducive to decoding. The method comprises: a receiving device converts a received optical signal so as to obtain information to be detected, the information to be detected comprising a plurality of packets, each packet comprising a plurality of symbols, the plurality of symbols being mapped onto at least one constellation point comprised in a constellation map of the optical signal, and the at least one constellation point being transmitted by means of at least two consecutive time slots; the receiving device obtains target joint soft information corresponding to a target packet, the target joint soft information being used to indicate various values of the target packet, and the target packet being one of the plurality of packets; and the receiving device performs forward error correction (FEC) decoding on the target joint soft information so as to obtain the original signal of the target packet.
