Optical receiving apparatus and method |
摘要 |
<p>An optical receiving apparatus compensates degradation of an optical signal received, based a division operation using the intensity of the optical signal. A receiving unit outputs a first electrical signal corresponding to the phase of the optical signal and a second electrical signal corresponding to the intensity of the optical signal. An analog first dividing unit and a second dividing unit divide the first electrical signal by the second electrical signal. A first ADC and a second ADC convert the divided electrical signal to a digital signal. An identifying unit identifies data of the optical signal based on calculation using the digital signal.</p> |
