摘要

【目的】

作为光信号发生器，发光二极管（LED）在可见光通信（VLC）系统中的关键作用不可忽视。然而，LED的静态非线性和频率响应问题经常引发VLC系统的信号失真和性能下降，迫切需要寻找创新的补偿方法。基于此，文章提出了一种前瞻性的解决方案。

【方法】

文章采用预失真方法进行VLC系统的非线性估计和补偿。文章详细分析了当前已有的相关解决方案，并将焦点放在LED非线性建模上，提出了一种基于幅度分解多项式（AFP）的自适应预失真器，旨在有效地弥补LED的非线性。

【结果】

数值仿真表明，文章所提方案在误码率（BER）、幅度调制/幅度调制（AM/AM）矫正和星座图性能方面表现出色。相对于传统的记忆多项式，文章所提方法具备更高的建模精度，归一化均方误差性能降低了15 dB以上。

【结论】

文章证明了基于AFP的自适应预失真器作为LED非线性补偿的有效性，提高了VLC系统的性能，而且为解决LED的静态非线性和频率响应问题提供了可行的解决途径。

Abstract

【Objective】

Light Emitting Diode (LED) is an important nonlinear optical signal generating device in Visible Light Communication (VLC) systems. The static nonlinearity of LED and the dynamic nonlinear memory effect caused by frequency response can lead to signal distortion and degrade the system performance.

【Methods】

The nonlinearity of LED can usually be compensated by estimating a pre-distortion model

and the wireless VLC is usually intensity modulated/directly detected.

【Results】

Therefore

the LED nonlinearity modeling is investigated

and an adaptive pre-distortion device based on Amplitude Factorization Polynomial (AFP) is proposed to compensate LED nonlinearity in this paper. Simulation results show that the proposed scheme exhibits good Bit Error Rate (BER)

Amplitude Modulation/Amplitude Modulation (AM/AM) correction and constellation diagram performance with higher modeling accuracy.

【Conclusion】

The normalized mean square error performance improvement of more than 15 dB compared with the traditional memory polynomial is achieved.
