Abstract

The invention discloses a signal processing method, device and signal receiver. The method includes: according to the verification relationship set during forward error correction coding, whether a phase jump occurs in the data segment of the detection signal and the degree of the phase jump occurs; according to the degree of the phase jump, the phase jump occurs Perform phase correction on the data segment; perform confidence correction on the data segment with phase jump and phase correction; perform forward error correction judgment decoding on the data segment after confidence correction, and output the processed data segment. The device is a device for implementing the method. The signal receiver is a signal receiver comprising the device. The signal processing method, device and signal receiver of the present invention greatly reduce the influence of phase jump misjudgment on judgment decoding by performing phase correction and confidence correction on the data segment of the signal, thereby solving the problem caused by phase jump. Bit error problem.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to a signal processing method, device and signal receiver. Background technique [0002] With the development of communication technology, the transmission rate of high-speed optical fiber transmission system is from 40Gb / s to 100Gb / s, even 400Gb / s, and coherent receiving technology is widely used. The main structure of the coherent receiving system is as follows: figure 1 Shown: At the sending end, the digital signal code stream is forward error correction coded by the forward error correction coding module, and the phase modulation module performs phase modulation before sending to the optical fiber link. At the receiving end, the receiving module coherently receives and demodulates the analog baseband signal through the optical fiber link; the analog-to-digital conversion module samples the analog baseband signal to obtain a multi-level digital signal; Domai...
