Application of digital predistortion linearization technology for 5G radio-over-fiber communication systems
With the development of 5G communication technology rapidly,radio-over-fiber communication systems play a crucial role in achieving high data transmission rate and low latency.However,it is often affected in this system by the nonlinear characteristics of radio frequency power amplifiers and optoelectronic components when processing high-frequency broadband 5G signals,leading to signal distortion problems.To solve this problem,the application and effectiveness of digital predistortion technology is deeply investigated in this paper.
