Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The technical contributions suffice publication for this journal. However, there are several minor presentation issues, given as follows.

1) The placement of Figures: Figures 6 to 12 seems not placed in the middle of text lines.

2) Please check the experimental Setting in Table I.

a) The electrical power of UV LED is 100mW? - is it optical power?

b) The FOV of receiver optical filter is 5 degrees? - it is 50 degrees?

Reviewer 2 Report

Comments and Suggestions for Authors

This paper proposed a UV communication solution based on varying the signal duty cycle to minimize error rates, and derived a closed-form expression for signal transmission error rates using a single-scattering model. Simulation and experimental results indicated that the proposed scheme exhibited importance in reducing the BER and optimizing system performance. However, some concerns should be carefully addressed before its publication.

 

1. In the abstract, the authors should shorten the background and address more about the novelty of the proposed scheme.

2. As mentioned in the abstract, the authors should provide more specific explanation for the different impact of the tailing effect on error rates in the UV systems with diverse speed.

3. All the variables in equations should be explained, such as Ks, Pray(u), and PMie(u) in Eq (2).

4. The symbols, such as “ksRay and ksMie” should be revised.

5. The sentence in Line 189 is not clearly explained.

6. In the simulation results, as in Fig. 8, 9, more numerical results should be analyzed.

7. The grammar mistakes, such as “From Figure 9. (a)”, “In Figure 9. (b)” should be revised.

The grammar mistakes, such as “From Figure 9. (a)”, “In Figure 9. (b)” should be revised.
