[摘要] 基于IEEE 802.15.7标准中色移键控（CSK）调制通信系统的检测方案，利用CSK调制的特性，提出了一种新的盲检测算法。该盲检测算法，利用CSK调制信号的性质在没有信道信息的情况下也可以对CSK信号进行解调，省略了信道估计模块，简化了系统。仿真发现，这种盲检测算法具有较好的误码率性能。

[Abstract] Color shift keying (CSK) is a modulation scheme proposed in IEEE 802.15.7. CSK is applicable to visible light communication systems with RGB LEDs. We propose a novel blind detection algorithm based on CSK modulation. This algorithm can demodulate a CSK signal by using the properties of CSK modulated signals in the absence of channel information. Simulation results show that the blind detection algorithm simplifies the system module and has better bit error rate performance.
