Title:
SIGNAL PROCESSING DEVICE, OPTICAL COMMUNICATION SYSTEM, AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/155775
Kind Code:
A1
Abstract:
An optical receiver (20) is provided with an electric signal generation unit (200), a first phase compensation unit (101), a distortion compensation unit (102), and a first dispersion compensation unit (400). The electric signal generation unit (200) generates an electric signal on the basis of a received optical signal. The first phase compensation unit (101) performs a phase rotation compensation process on the electric signal generated by the electric signal generation unit (200). The distortion compensation unit (102) performs a dispersion compensation process and a phase rotation compensation process at least once in the stated order on the electric signal after the same has been compensated by the first phase compensation unit (101). The electric signal generation unit (200), the first phase compensation unit (101), and the distortion compensation unit (102) are incorporated into a single semiconductor device.
