Broadband Wireless Communication Systems for Vacuum Tube High-Speed Flying Train

Round 1

Reviewer 1 Report

This paper develops a rail transportation approach in the ultra high-speech scenario with low mechanical friction, low air resistance, which makes low level of noise.  For this aim, a list of challenges associated with   are investigated  with the wireless  communication for vactrain. Afterwards, a leaky waveguide solution with simple architecture is developed for wireless coverage in the vacuum tube. The simulation results show the effectiveness of the proposed method.

Reviewer 2 Report

The authors made an effort to improve the paper. I appreciate that.

For the type of work, that is not usual (in my opinion), I think that several references to other works are missed and could be considered in order to reduce the lack of technical explanation in the paper.

For instance, for working with Wireless Sensor Networks (WSNs), tracking, control systems, prediction, automatic driving you can cite different advanced particle filtering methods such as:

L. Martino, J. Read, V. Elvira, F. Louzada, "Cooperative Parallel Particle Filters for on-Line Model Selection and Applications to Urban Mobility" Digital Signal Processing Volume 60, Pages: 172-185, 2017

V. Elvira, L. Martino, M. F. Bugallo, P. M. Djuric, "Elucidating the auxiliary particle filter via multiple importance sampling", IEEE Signal Processing Magazine, 2019.

These are important  (old and recent) works with several possible applications. Improving the discussion of the state-of-the-art can increase the comprehension and the impact of your work. It is important to add references in your work since there is a lack of technicalities. These changes are essential for the publication.

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

This paper introduces a new rail transportation approach in the ultra-high-speed scenario. For this purpose, first, a list of the unique challenges and opportunities associated with wireless communication for vactrain is summarized. Afterward, an analysis of the bandwidth and Quality of Service (QoS) are provided. Simulation test studies are performed to evaluate the proposed strategy. Here, I have provided some comments as follows:
1-There is no literature review on wireless communications in the introductions.
2-Authors must explain the main contributions of the paper in the introduction.
3-Design implementations and formula must be moved to the main body.
4- A comparison with other methods must be made in the paper.

Reviewer 2 Report

I believe that the degree of novelty of the paper is too small for accepting for publication (at least in this journal).

I suggest to submit to other kind of journals, with impact factor or more focuses in your application.
