Power Control of Reed–Solomon-Coded OFDM Systems in Rayleigh Fading Channels

Round 1

Reviewer 1 Report (Previous Reviewer 1)

The paper is well-drafted and organized, but they're few changes are identified.

1. The paper has good mathematical and simulation analysis but what about other coded OFDM systems!!!, I think you need to do a performance comparison table of other coded OFDM systems in open literature with the proposed system.

2. There are a few grammatical errors and advised authors to proofread the manuscript to avoid them.

3. Authors are advised to follow strictly the MDPI Journal format and there are no author contributions as well as the conflicts statement and advised to include them

Reviewer 2 Report (Previous Reviewer 2)

The author has considered the use of power control of Reed Solomon coded OFDM systems in Rayleigh fading channels. The paper is now ready to be published.

Author Response

Thank you.

Round 2

Reviewer 1 Report (Previous Reviewer 1)

The authors addressed all the reviewer comments and suggestions and they are right order. The paper would be accepted in present form

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

The paper is original with good mathematical analysis but most of the relevant information is given in Appendix sections. It is advised authors to increase literature review papers and support the work by enhancing the introduction section.

Most of the started was started with "we", advised authors to avoid and try improve the readability.

Try to add a comparison table between existing similar works and proposed work and it must be needed

Reviewer 2 Report

The author considers power control of RS coded OFDM systems in Rayleigh fading channels. The paper has several drawbacks, namely:

1- Topic is not up to date.

2- Title and content of the Abstract of paper are not related.

3- Very low novelty, significance of content.

4- All references are from past century.

5- WER is only defined at line 227 in Conclusions section.

6- The system model presented does not include any interleaving, so the assumptions taken are not valid.

7- On Results section what was the size of the IFFT (and DFT) considered?

8- Why have you made simulations in one single case? You should provide simulations for all your results, to check the accuracy of your analytical results. 

9- All your analytical results presented in section Results are upper bounds.

10- You never mention in your paper feadback needed so that the transmitter knows the fading amplitude. What channel are you considering?

11- Please, name a few real systems where your paper might be developed? IoT? 5G? Satellite link?

Reviewer 3 Report

great paper, I have no comments
