Abstract

Filter bank multicarrier (FBMC) has become a promising candidate to replace conventional orthogonal frequency-division multiplexing (OFDM) scheme in 5G technology due to its better spectral confinement which results in a reduced inter-channel interference (ICI). However, the viability of using FBMC in visible light communication has not been verified. In this work we present the first experimental validation of the DC-biased optical filter bank multicarrier (DCO-FBMC) modulation scheme over a free-space optical channel. Under different receiving powers, up to three times bit error rate performance improvement has been achieved using DCO-FBMC with different overlapping factors compared to that of conventional DCO-OFDM.
可见光通信采用直流偏置光滤波器组多载波调制
在5G技术中,滤波器组多载波(FBMC)由于具有更好的频谱约束,减少了信道间干扰(ICI),已成为取代传统正交频分复用(OFDM)方案的有希望的候选方案。然而,在可见光通信中使用FBMC的可行性尚未得到验证。在这项工作中,我们提出了在自由空间光通道上的直流偏置光滤波器组多载波(DCO-FBMC)调制方案的第一个实验验证。在不同的接收功率下,采用不同重叠因子的DCO-FBMC与传统DCO-OFDM相比,误码率提高了3倍。
