摘　　要：LED信道模型是一种非稳态的信道模型,它通过在良好状态和不良状态之间进行切换,来更好的拟合实际信道环境。Jakes模型是该信道的重要组成部分,它直接影响了LED可见光信道模型的性能。在光信号通信传输过程中,不同的保持距离,信道状态的转换的情况是不同的。本文通过对Jakes模型进行改进,降低了实现的复杂度。还通过将保持距离设置为变量,来更好的逼近实际信道环境。LED channel model is a non steady state channel model.It can better fit the actual channel environment by switching between good and bad states.Jakes model is an important component of this channel,and it directly affects the performance of LED visible channel model.In the transmission process of optical signal communication,the change of channel status is different with different holding distance.In this paper,the complexity of the implementation is reduced by improving the Jakes model.It is also better to approach the actual channel environment by setting the distance as variables.
