Patent Searching and Data


Title:
OPTICAL RECEIVER, SIGNAL REPRODUCING METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2010219651
Kind Code:
A
Abstract:

To accurately reproduce original data signals corresponding to received signals.

The optical receiver receives optical signals which are transmitted from an optical transmitter and data signals of which are modulated. The received optical signals are converted to electric signals corresponding to the phase of the optical signals, an identification threshold to be a reference for reproducing the data signals is calculated on the basis of the amplitude of the electric signals, and the data signals are reproduced from differential signals which are signals calculated from the electric signals with the calculated identification threshold as a reference.
