OFDM-ROF系统中峰均比抑制及预失真技术的研究
Research on PAPR restrain and pre-distortion technique in OFDM-ROF system
摘要
Abstract
For the nonlinear analysis of OFDM-ROF link devices respectively is complex, this paper proposed the OFDM-ROF joint system simulation analysis based on MATLAB,used the peak offset method and memory polynomial pre-distortion technol-ogy. The final AM/AM characteristics, spectrum, constellation chart and convergence error simulation results show that the system has a great improvement, it illustrates the feasibility using the suppression of PAPR and pre-distortion technology to OFUM-ROF system.关键词
