The method for feedback control of the coherent receiver includes: obtaining a feedback control quantity according to a digital signal converted by an Analog-to-Digital Converter (ADC); and adjusting a signal amplitude output by a Transimpedance Amplifier (TIA) and a direct current component of an offset T device according to the feedback control quantity, until an analog signal input into the ADC is in a sampling range of the ADC, where the TIA is serially connected to the offset T device and then is connected to the ADC. Present invention has the following advantages: enabling the analog signal to adapt to the ADC sampling best, maximizing an effective information quantity sampled by the ADC and better supporting subsequent processing of a Digital Signal Processing (DSP) unit, thereby improving a coherent receiving performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus, and system for feedback control of coherent receiver","description":"A method, an apparatus, and a system for feedback control of a coherent receiver are provided.
