Optimized Polar Codes as Forward Error Correction Coding for Digital Video Broadcasting Systems

Round 1

Reviewer 1 Report

The authors presented an interesting and new method to enhance the performance of DVB systems using polar codes as FEC coding.

Several minor suggestions for improving the manuscript.

1. I suggest expanding the literature review with the following important studies in this area: Pratschner, S.; Tahir, B .; Marijanovic, L.; Mussbah, M.; Kirev, K.; Nissel, R.; Schwarz, S.; Rupp, M. Versatile Mobile Communications Simulation: The Vienna 5G Link Level Simulator, 2018. Available online: http://arxiv.org/pdf/1806.03929v1 and Babar, Z.; Kaykac Egilmez, Z.B.; Xiang, L.; Chandra, D.; Maunder, R.G.; Ng, S.X.; Hanzo, L. Polar Codes and Their Quantum-Domain Counterparts. IEEE Commun. Surv. Tutorials 2020, 22, 123-155, doi: 10.1109/COMST.2019.2937923.

2. The ordinate axis should be indicated in Figure 4.

3. Describe future research.

Reviewer 2 Report

The article has some merit but authors need to signify the novelty of this work in terms of following comments and observations:

1. SOA should be enriched with recent advancements similar to this work and provide motivation that what are the limitations in the present literature that made this work significant.
2. A higher-level abstract form of pseudo-code should be added.
3. Why comparison in Fig. 8 and 9 is restricted w.r.t  LDPC ?
4. What is the novelty of the paper? Please motivate that what does this work proves novel?
5. The procedure defined in Fig. 3 is well known. How is it novel or what is the input by the authors?https://pdfs.semanticscholar.org/8141/a3e793ad3154ac9d4131df63ae6ee1c715ee.pdf
6. Include the following results:  a.  FER in addition to BER?
   b. Is it possible to see a number of error bits counted for set data frames for different signal-to-noise ratio (SNR)?
   c. Throughput vs SNR
7. Why BPSK is chosen for AWGN? Why not utilize a more NLOS complex environment with TDL-A,B,C with a higher QAM modulation?
8. A table should be added with all the simulation settings. Are the settings 3GPP compliant? Mention Release.

Round 2

Reviewer 2 Report

The comments that I had mentioned in my previous review have been met. I would just like to mention to the authors that 3GPP compliancy is an important aspect that should not be left unanswered. For future works, authors should keep in mind that standardization is very important and they should address this 3GPP aspect as well in their simulators.
