Hardware-Efficient Blind Frequency Offset Estimation for Spectral-Efficient Digital Subcarrier Multiplexing Systems

Hong Lv et al.

Summary: This article proposes a blind frequency offset estimation (FOE) method for high spectral-efficient DSM signals, with hardware efficiency, a wide range of offset detection, and high accuracy. By reusing spectral information, the method achieves chromatic dispersion compensation (CDC) and demonstrates robustness against transmission impairments. Experimental verification is conducted for the performance of the proposed method.

Hardware-efficient blind frequency offset estimation for digital subcarrier multiplexing signals

Meng Xiang et al.

Summary: A hardware-efficient blind FOE solution for DSM signals is proposed by monitoring spectral dips in the frequency domain and using a smoothing filter for increased estimation accuracy. The method is robust to various transmission impairments and has been verified numerically and experimentally under different scenarios.
