The author investigates the monitoring methods for fine adjustment of the previously proposed on-chip architecture for frequency multiplication and translation of harmonics by design. Digital signal processing (DSP) algorithms are utilized to create an optimized microwave photonic integrated circuit functionality toward automated frequency multiplication. The implemented DSP algorithms are formed on discrete Fourier transform and optimization-based algorithms (Greedy and gradient-based algorithms), which are analytically derived and numerically compared based on the accuracy and speed of convergence criteria.

微波光子集成电路中智能相位调整的设计，以实现自动倍频

作者研究了用于微调先前提出的用于频率倍增和谐波转换的片上架构的监控方法。利用数字信号处理（DSP）算法来创建优化的微波光子集成电路功能，以实现自动倍频。实施的DSP算法是基于离散傅里叶变换和基于优化的算法（基于贪婪算法和基于梯度的算法）形成的，这些算法根据收敛标准的准确性和速度进行分析得出并进行数值比较。
