提出了一种递归方法，用来计算当室内反射光源视为Lambertian光源时，室内自由空间信道的冲击响应。-A recursive method for evaluating the impulse response of an indoor free-space optical channel with Lambertian reflectors.

For free space path loss, fc=1.5GHz (Carrier frequency) If we take different antenna gains such as 1.(Gt=1,Gr=1)and 2.(Gt=1,Gr=0.5)and 3.(Gt=0.5,Gr=0.5) When we reduce the antenna gains (i.e. the transmitting gain or the receiving gain) there is

shows the free-space path loss at the carrier frequency of fc = 1.5 GHz for different antenna gains as the distance varies
