Reviewer 2 Report
1. Line no 22, There should not be a gap between T and Hz.
2. Very little parts of the large-scale antenna system are discussed.
3. In 189 and 190, mm-wave is mentioned but none of the results are properly justifying this frequency. The author should explain this.

Reviewer 4 Report
The paper proposes a new fast time-delay estimation method based on polynomial inversion, under requirements of high precision and low computational complexity in wideband large-scale antenna systems.
The contributions of the article with respect to other works in the literature are not sufficiently explained. The authors should highlight the contributions of the paper and make comparisons with previous works.
The notation used is not clear enough for the reader. Each of the terms that appear in the different mathematical expressions should be explained.
It is necessary to revise the wording of the article, since some sentences are not clear.
