碩士 === 國立臺北科技大學 === 光電工程系 === 107 === In this paper, we will generate wireless signals by using software-defined radio (SDR) and analyze them under the architecture of intensity and phase modulation. First, the constellation and error vector magnitude (EVM) will be used to determine the quality of the signal in both architectures. In order to better conform to the actual application scenario, the modulated signal passes through the long-distance fiber is followed by a antenna link to simulate future practical application scenarios. The results show that the signals generated by the USRP not only provides a high degree of flexibility but also good transmission quality. It is believed that the analysis and discussion of this experiment will contribute to the development of optical communication in the future.
