OFDM-ROF系统中峰均比抑制及预失真技术的研究

摘要

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.%针对OFDM-ROF链路中各器件非线性分别分析的复杂性,就OFDM-ROF系统提出了基于MATLAB的联合仿真系统分析,采用了峰值抵消法和记忆多项式预失真技术;最终的AM/AM特性、频谱、星座图和收敛误差仿真结果显示该系统较原来的系统有很大的改进,说明了对OFDM-ROF系统采用峰均比抑制以及预失真技术的可行性.
