Embodiment Construction
[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with specific embodiments.
[0047] A wireless ultraviolet light scattering channel estimation method based on deep learning, the overall principle model diagram is as follows image 3 As shown, the specific steps are as follows:
[0048] Step 1. First, model and simulate the single scattering of wireless ultraviolet light to form a channel model of non-line-of-sight single scattering of ultraviolet light, and then add conditions such as noise and distortion, such as Figure 4 As shown, in the figure β T and beta R are the elevation angles of the transmitter and receiver, respectively, θ T is the half angle of beam divergence angle, θ R Half angle of receiving field of view, θ S is the scattering angle, V is the common scatterer, r 1 and r 2 are the distances from the sending end a...
