摘要

我们通过实验证明了在标准光纤链路上部署数字化射频传输的微波信号的高性能传输。采用带通采样技术，以16 QAM调制格式和6msymbol /s数据速率对2.475 GHz微波信号(WiMAX)进行数字化处理，并在20 km光链路上传输。使用8位分辨率的ADC，成功地传输和恢复了WiMAX信号，误差矢量幅度非常好(~1.77)。

Experimental demonstration of digitized RF transport over optical fiber links

We experimentally demonstrate high performance transmission of microwave signals deploying digitized RF transport over a standard optical fiber link. Bandpass sampling technique is used to digitize a 2.475 GHz microwave signal (WiMAX) with a 16 QAM modulation format and 6 MSymbol/s data rate and is transmitted over a 20 km optical link. Using an ADC with 8 bit resolution, a WiMAX signal was successfully transmitted and recovered with very good error-vector magnitudes (~1.77).
