摘要

本文研究了直接调制VCSEL产生的OFDM信号在OM-3多模光纤中通过实验测量估计的光通道上的传输。仿真结果表明，VCSEL的非线性L-I曲线限制了系统的性能。结果表明，在这种情况下，通过对发射机进行预失真可以提高系统的性能。

Signal predistortion for nonlinear transmitters in direct-detection OFDM over multimode fibers

This paper investigates the transmission of OFDM signals, generated by a directly-modulated VCSEL, over an optical channel estimated from experimental measurements in OM-3 multimode fibers. Simulation results indicate limitations on the system performance due to the nonlinear L-I curve of the VCSEL. We show that, in these conditions, the system performance can be improved by transmitter predistortion.
