Title:
RECEIVING DEVICE AND LOCAL LIGHT EMISSION CONTROL METHOD
Document Type and Number:
Japanese Patent JP2018006836
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a receiving device or the like capable of suppressing power consumption required for local light emission.SOLUTION: A receiving device comprises a light source, a multiplexing part, a conversion part, a demodulation part, a correction part and a control part. The light source outputs local light emission. The multiplexing part acquires an optical signal by interfering a received signal with the local light emission. The conversion part converts the optical signal into an electric signal. The demodulation part acquires a demodulated signal by demodulating the electric signal. The correction part performs error correction on the demodulated signal. A first monitor part acquires a signal correction amount and/or an error rate from the correction part. Based on the signal correction amount and/or the error rate, the control part controls the light source in such a manner that an output intensity of the local light emission is adjusted.SELECTED DRAWING: Figure 2
