Round 1

Reviewer 1 Report

It is interesting paper presenting linearization method for RF PA. I have few minor comments. 1 .Figures are not fully shown in the paper. It should be updated. 2. There are some typos in line 261, 269, and more. Please carefully update all the errors. 3. English should be improved for the better readability. 4. Are the Figure 3 ~ 6 measurement data? Please clearly state it.

Reviewer 2 Report

The authors presented the Weighted Memory Polynomial W-MPM algorithm and validated its implementation and measured its performance. 

Please specify the signal used to plot AMAM and AMPM graphs: the signal bandwidth, the PAPR... 

Can the author comment on using Direct Learning with this model? Can this model be extended to GMP and make it W-GMP? 

The overall quality of work is good. 

Minor spelling errors and typos. Some formatting, text alignment is needed to fit the graphs in the page

Add figure numbers in lines 261 269 282 332 (??)
