Round 1
Reviewer 1 Report
The paper presents an interesting subject, but there are a few issues that need to be solved:
- figures 2 and 3 should be introduced after they are mentioned in text. Same for figures 8, 16, 17, 20.
- the authors mention in the paper that a contribution is the proposed CHT, can you give more details? Later it is mentioned that the CH matrix is taken from [20]. Please emphasize more the degree of novelty brought by this paper.
- maybe a table can be made for the last figures, for a better view of the obtained values
- the conclusion part can be more developed
- Figure 6 is for user 3 and in such case; the system provides significant BER performance as 233 compared to other implemented channel coding techniques. - without ";".

Reviewer 2 Report
CoMP is an effective technique for controlling interference at the cell edge. The authors proposed an analytical framework of CP-free multi-user OFDM system for CoMP at mmWave.
Follow the comments and instructions below.
- Authors should add more papers of related studies.
- The authors should describe in more detail why they considered the parameters of the block diagram in Figure 3 and what they provide to CoMP-JT.
- The authors should describe in more detail why Equations are needed and how they contribute to a CP-free multi-user OFDM system.
- Authors should present procedures of Algorithm for “without HPA” in section 2.3.1 and “with HPA” in section 2.3.2.

Reviewer 3 Report
- Despite the authors' survey of the related works, the past research gaps are not indicated significant. This is the key point why you proceed with this study. The authors are suggested to use a table to list the used technologies, merits, and demerits, etc.
- The users are suggested to use a flowchart to present how to proceed with their study.
- What are the limitations of your study?

Round 2
Reviewer 2 Report
- The authors carefully followed the reviewer's comments and suggestions.
- The authors have revised many suggestions of a reviewer, but the parameters of the columns of the block diagram in Figure 3 is required more explanations.

Reviewer 3 Report
The authors have fixed most previous concerns. But the proposed flowchart which presents how to proceed with your study does not use the diamond diagram to illustrate if go back to the previous step. Please check it before publication.
