Abstract
Fiber-optic transmission of broadband wireless communication signals based on source and transmission integration is proposed and experimentally demonstrated. In this scheme, a radio-over-fiber (RoF) link is employed to transmit the broadband wireless communication signal. Using the long optical fiber in the RoF link, a dual-loop optoelectronic oscillator (OEO) localized in the centralized unit (CU) can be established to up-convert the broadband wireless communication signal to a higher frequency. In such a case, the transmitted wireless communication signal can be directly emitted by the antenna, further streamlining the remote active antenna unit (AAU) structure. The proposed wireless communication system based on source and transmission integration is experimentally investigated. In the experiment, a 256-QAM signal centered at 1 GHz is transmitted by the high-power RoF link involving a spool of single-mode fiber (SMF) with a length of 1 km and then successfully up-converted to 11 GHz. In addition, the measured error vector magnitudes (EVMs) of the wireless communication signals with bandwidths of 26 MHz, 65 MHz, and 130 MHz are held below 3.5%, which satisfies the requirement of TS38.101.
