In the channel estimation for ultraviolet communication, the single scattering power is usually used to approximate the received total power. This approximation error is affected by the transceiver configuration. Here, we employ the proportion of received single scattering power in received total power to indicate the approximation error of the single scattering model in different configurations. This is useful for reducing the approximation error by selecting a more appropriate transceiver configuration.

With the recent advances of ultraviolet (UV) source and detectors in the solar blind wavelength regime, UV communication system has attracted increasing attention. The non-line-of-sight (NLOS) channel modeling of UV communication has gradually become the core issue [

In this work, the proportion of the received single scattering power in the received total power is employed as an indicator to evaluate the approximation error and the effectiveness of the single scattering model under different transceiver configurations. The simulation results demonstrate that this proportion decreases with the increase of elevation angle, field-of-view (FOV) angle and the communication range. Thus, the effective range of single scattering model is limited by the transceiver configuration. We also find that the approximation error of the single scattering model in UV communication can be reduced by selecting a more appropriate configuration.

We take multiple scattering model [

First, the proportion under different communication ranges r and transmitter elevation angles θ T are simulated by multiple scattering model [

Second,

Third, in addition to two elevation angles and communication range, the changes in receiver FOV (i.e., β R ) also affect the proportion, as shown in

Based on the preceding analysis, the proportion of received single scattering power in received total power increases with the decrease of elevation angles and FOV angle. Three kinds of NLOS transceiver configuration in small elevation angle and small FOV case are shown in

( β T = 1 ˚ , β R = 25 ˚ , θ T = 65 ˚ , θ R = 15 ˚ ) .

The proportion of the received single scattering power in the received total power is employed to indicate the impacts of transceiver configuration. We use the proportion to analyze the approximation error and the effective range of single scattering model. The results show that the effective range of single scattering model is limited by the transceiver configuration. Furthermore, the approximation error of single scattering model can be negligible in the case of small elevation angles and small FOV, even in long range communication system.
