Digitized RF transmission over fiber

Abstract

Our studies have shown that a digitized radio- over-fiber system based on bandpass sampling with an analog-to-digital converter having a resolution of 8 b is sufficient to construct a high-performance, cost-effective link that can allow easy integration of wireless backhaul with optical communication infrastructure. We also show that the performance of the digitized system is predominantly limited by the performance of the analog-to-digital converter used, with its quantization noise limiting the performance for the lower values of resolution (<6 b) and its jitter limiting the performance at the higher resolutions (>7 b).
