摘要

提出了一种基于码移键控(CSK)调制的多用户室内可见光通信(VLC)系统。所提出的CSK方案采用M个信号波形，每个波形都是由单个基本PN码的圆移位获得的。在此方案中，研究了存在干扰和/或来自其他用户的干扰时的性能。此外，还将CSK的系统性能与传统的开关键控(OOK)系统进行了比较。仿真结果表明，在多用户系统中，CSK比OOK更可靠。

Multiuser Interference Mitigation using CSK in Indoor Visible Light Communications

In this paper, we present a novel multiuser indoor visible light communication (VLC) system based on code shift keying (CSK) modulation. The proposed CSK scheme employs M signaling waveforms each obtained from the circular shift of a single fundamental PN code. In this proposed scheme, the performance is investigated in the presence of jamming and/or interference from other users. In addition, the system performance of CSK is compared with traditional on-off keying (OOK) based system. The simulation results show that the proposed CSK is more reliable than OOK in multiuser systems.
