Abstract

We experimentally demonstrate high-performance transmission of multiple distinct microwave signals via digitized radio-frequency (RF) transport over a 20-km standard optical fiber link. A bandpass sampling technique is used to digitize a 2.475-GHz wireless signal [worldwide interoperability for microwave access (WiMAX)] carrying 6-MSymbol/s data in 16 quadrature amplitude modulation format and a 1.95-GHz wireless signal [global system for mobile communication (GSM)] with 270.833-kb/s data in Gaussian minimum shift keying modulation format. Using an analog-to-digital converter with 8-bit resolution, the WiMAX and GSM RF signals are simultaneously transmitted and recovered successfully with very good error-vector magnitudes of ~3.44 and ~1.42, respectively.
