摘要

在室内光信道中，由于多径传输引起的码间干扰(ISI)阻碍了高数据速率传输。为了提高传输质量，研究了一种新的多波长脉冲位置调制方法。在该策略中，实现了并行传输，从而降低了每通道的数据速率，从而减少了ISI的影响。此外，该策略还在预先确定的并行分支中实现了并行编码技术。这种并行编码在不改变系统数据速率的情况下纠正错误。仿真结果表明，在不降低总数据速率的情况下，这些方法的组合可以实现高质量的传输。

Optical multi-wavelength PPM for high data rate transmission on indoor channels

In indoor optical channels, intersymbol interference (ISI) due to the multipath propagation prevents high data rate transmission. A new optical multi-wavelength PPM (pulse position modulation) has been investigated for improving the quality of transmission. In this strategy, parallel transmission is accomplished which lowers the data rate per channel and thus reduces the effect of ISI. Furthermore, this strategy also implements a parallel coding technique in the predetermined parallel branches. This parallel coding corrects errors without changing the system data rate. The simulation results show that a combination of these methods can achieve high quality transmission without reduction of the total data rate.
