多信道数字与模拟RoF系统性能比较
Performance comparision between multichannel digital radio over fiber system and analogue radio over fiber system
摘要
Abstract
In this article,a comprehensively comparision is made between multichannel digital RoF and analog RoF transmission scheme and their performances,and it has been discussed about how to realize the frequency conversion only with a single ADC or DAC under the theory of bandpass sampling.Then to simulate and to comprehensively make comparision about the nonlinearity products,and the result was simulated by OptiSystem.Both theory and experiment suggest a better performance and cost-effective in digital RoF link,especially for long-haul fiber radio networks.关键词
