基于发光二极管(LED)的可见光通信(VLC)已经成为下一代高速室内无线通信的潜在候选者。由于LED的调制带宽有限，为了克服峰值平均功率比(PAPR)高、性能损失严重的码间干扰(ISI)，正交频分复用(Ofdm)调制在VLC系统中尤其受到青睐。本文提出并实验证明了一种新的Zadoff-Chu矩阵(ZCM)预编码方案，该方案不仅可以降低PAPR，而且可以提供均匀的信噪比(SNR)。理论分析和仿真表明，与传统的预编码方案相比，该方案获得了更好的PAPR性能。实验结果进一步验证了误码率性能的改善，在传输数据速率为50Mb/S时，误码率均低于前向纠错前7%3.8×10−3的极限。
Light-emitting diode- (LED-) based visible light communication (VLC) has become a potential candidate for next generation high-speed indoor wireless communication. Due to the limited modulation bandwidth of the LED, orthogonal frequency division multiplexing (OFDM) modulation is particularly preferred in the VLC system to overcome the ISI, which suffers from the high peak-to-average power ratio (PAPR) and leads to severe performance loss. In this paper, we propose and experimentally demonstrate a novel Zadoff-Chu matrix (ZCM) precoding scheme, which can not only reduce the PAPR, but also provide uniform signal-to-noise ratio (SNR) profile. The theoretical analysis and simulation show that the proposed scheme achieves better PAPR performance compared with the traditional precoding schemes. The experimental demonstration further validates the bit error rate (BER) performance improvement, where the measured BERs are all below the 7% pre-forward error correction (pre-FEC) limit of 3.8 × 10−3 when the transmitted data rate is 50 Mb/s.
