First of all, thank you for the good research paper and presentation contents. I would like to know more about the research environment used in this study, and also in detail about the operating systems, development languages and software libraries you used. Thanks for your comment. The simulations of this study have been performed using a MATLAB environment. The theoretical analysis of this work is only a function of the channel coefficient, a random variable that has different value per network realization. Hence, there is no specific libraries were used. All the provided simulation results are obtained via Monte Carlo simulations through 100000 network realizations; each realization has a randomly generated channel.

Thank you for a very clear presentation. My question has three parts: 1- is your approach applicable on other network types, other than NDR? 2- did you consider the issue of link lost with the relays? 3- was this research examined under high network congestion? and what is your findings? Thanks for your comment. 1- Yes, the proposed approach and its theoritical analysis can be applied to any network type that is involving two relays with the objective of maximizing the sum rate of two symbols at the destination. However, if the network type has only one relay, the theoritical analysis would be reduced to simple dual hop cooperative network mode. 2- yes, as the proposed relay selection technique, selects the 'best available' pair of relays that maximize the end-to-end achievable capacity for the destination user. 3-yes, all the presented simulation results were acquired through Monte Carlo simulations of 100000 network realizations.

Dear Author, you have a very good research. However, I would like to know if the technology today capable of implementing your proposed scheme? Is there an existing technology almost similar to your proposal that has been deployed in real world environment? Thank you and stay safe. Thanks a lot for your comment. although the proposed model based on NOMA is introducing the theoretical analysis and its related simulation results, several works in the literature studied implementing NOMA in practical communication systems. This can be performed through real-time experimentation and studying practical challenges and their effects. for example, the following recent work; Y. Qi, X. Zhang and M. Vaezi, "Over-the-Air Implementation of NOMA: New Experiments and Future Directions," in IEEE Access, vol. 9, pp. 135828-135844, 2021.

thank you for your presentation. Have you considered an imperfect CSI?
