Abstract

The invention provides a high-speed and high-precision photo-analog-digital conversion device capable of achieving intelligent signal processing. Through the learning capability of a deep learning technology, a nonlinear response and a channel mismatch effect of the high-speed photo-analog-digital conversion system are learnt, deep network parameters are optimally configured, deterioration of theperformance of a photo-analog-digital conversion system by nonlinear distortion and channel mismatch distortion can be effectively removed in real time, and performance indexes of the photo-analog-digital conversion system can be effectively increased. Besides, through the induction and deduction capability of the deep learning technology, intelligent signal processing of an input signal can be achieved, and a digital signal which meets requirements is provided for a user, which has a very important effect on improving the performance of a microwave photon system, like a microwave photon radarand a photo communication system, needing high sampling speed, time precision and sampling precision and also improving the signal processing capability of the system under complex conditions.

Description

technical field [0001] The invention relates to the field of photon information processing, in particular to a high-speed and high-precision optical analog-to-digital conversion device and a conversion method that can realize intelligent signal processing. Background technique [0002] An analog-to-digital converter (hereinafter referred to as ADC) is a tool that converts an analog input signal into a digital signal that can be represented by a computer. It is a bridge connecting the analog world and computer signal processing, and is the basis for signal storage, transmission, and processing. Research on ADCs in the field of electronics has developed rapidly. In recent decades, electronic analog-to-digital converters (hereinafter referred to as EADCs) have made great progress toward high sampling rates and high precision. The internationally commercial EADC chip can already achieve a sampling rate of 30GS / s and an effective number of bits of 5.5. However, due to the inhere...
