Abstract :
In this paper, we propose a bit resolution enhancement technique employing oversampling and decimation for digitized radio-over-fiber (DRoF) transport. This technique reduces the overall bit rate for the optical link as well as reduces the hardware requirements on optoelectronics devices in the DRoF link. By using bit resolution enhanced DRoF technique, the overall data rate can be reduced from 4 Gbps to 1.5 Gbps while maintaining similar EVM performance for transporting the same wireless signals.
