摘要
光子学压缩感知技术是近年来发展迅速的一种新型频谱感知技术,以远低于奈奎斯特(Nyquist)率对信号进行采样,大大提高了频谱测量范围和频率测量精度,为宽频稀疏信号的感知和测量提供了有效的解决方法。重点介绍了目前几种光子学压缩感知方法及其最新研究进展,分析比较了各自的优缺点和应用范围,探讨了下一步深入研究的方向。
Photonics compressed sensing technology is a new spectrum sensing technology growed up rapidly in recent years, which could take a sample to signal with a rate that is much lower than the Nyquist sampling rate. It improve the spectrum measurement range and the signal measurement accuracy greatly, which pro- vides an effective solution for the fxequency measurement of broadband sparse signal. Highlights several kinds of photonics compressed sensing implementation, analysis and comparison of the advantages and disadvan- tages and applications, discusses next direction for further research.
