Title:
SIGNAL COMPENSATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/101255
Kind Code:
A1
Abstract:
Disclosed are a signal compensation method and device, comprising: receiving an input signal sequence suffering from ISI interference, and using a first filtering coefficient to perform filtering compensation on the received signal sequence, to obtain a first compensation signal sequence; using a balance filtering coefficient to perform filtering compensation on the first compensation signal sequence, to obtain a balance compensation result, the balance filtering coefficient being obtained by adjusting an adjacent balance filtering coefficient used last time via a first compensation error; and performing sequence estimation on the received balance compensation result and outputting same. Since a first compensation error is generated by a back-end compensation module, the first compensation error is used to adjust a balance filtering coefficient in an iterative way, and the balance filtering coefficient is used to perform filtering compensation on a first compensation signal sequence, thereby effectively compensating for a signal sequence suffering from ISI interference, and improving the system performance of optical fibre communication.
