论文摘要
我们提出并实验证明了基于两个光源的重叠以产生多压振幅的效果的新混合代码结构。我们还提出了用于基于多级的OCC系统的有效的极性逆转阈值（RRT）算法。然后考虑到SPO问题，提出了一种新型的自适应抽样方法（ASM），可以有效地减轻SPO的问题并进一步增强多级OCC的性能。证明可以通过应用提出的两种算法来实现8.4 kbit/s的数据速率。
We proposed and experimentally demonstrated a new hybrid code structure based on the overlapping of two light sources to produce the effect of multi-voltage amplitudes. And we also proposed an efficient polarity reversal threshold (RRT) algorithm for multilevel based OCC system. Then taking the issue of SPO into account, a novel adaptive sampling method (ASM) is proposed, which can effectively alleviate the problem of SPO and further enhance the performance of multilevel OCC. It is demonstrated that a data rate of 8.4 Kbit/s can be achieved by applying the proposed two algorithms.
