Regularized Zero-Forcing Dirty Paper Precoding in a High-Throughput Satellite Communication System
Round 1
Reviewer 1 Report
This is an intriguing study on satellite communication systems. The authors proposed a new precoding algorithm to regularize zero-forcing dirty paper and numerically demonstrated the advantages of the proposed regularized zero-forcing dirty paper precoding algorithm over the conventional zero-forcing dirty paper coding in terms of the influence of system noise. The study was good, the paper is well structured, and is suggested as suitable for publication.

The article has been further modified and polished to make the sentence more fluent and the expression more complete and accurate.
Reviewer 2 Report
The paper by Mingchuan Yang et al is devited to detailed studying a regularized zero-forcing dirty paper precoding in high-throughput Satellite Communication System. The authors have studied the possibilities to maximize the available data rate and spectrum utilization efficiency. In particular, the authors have presented a forward link model considering the effects of free space loss, rainfall attenuation and beam gain and improved the known classical low-complexity precoding algorithm of zero-forcing, in particular, in order to solve the problem of co-frequency interference. It has been studied the regularized zero-forcing precoding algorithm with considering the influence of system noise. A low complexity regularized zero-forcing dirty paper precoding algorithm and the corresponding modelling results are presented.
The paper by by Mingchuan Yang et al has undoubtedly the significant scientific merits, is of great theoretical and practical importance, and is definitely recommended for publication in the journal "Electronics" (MDPI).
The only minor editorial remarks are related to the possible expansion of the list of references in order to take into account the possible wishes and questions of readers. In particular, it makes sense to add the general references describing the physical and technical consequences of the effects of free space loss, rainfall attenuation and beam gain in the studied satellite communication system problematics (at the discretion of the authors).
