Thank you for your slide presentation. Can you please explain what is the contribution of this research? RoF/WDM-RoF sytem is a promising technique for providing broadband and high capacity wireless communication services, but suffers from nonlinear impairments. This work demonstates that reservoir computing is an efficient way to do the equalization of OFDM signal.

For some reasons my question has been deleted. I would be interested to get more details on the size of the training and testing datasets. Thank you. Sure. I am pleased to answer it again. For the RoF system, the size of the training and testing size are 1*12500, 1*25000, respectively, while for WDM-RoF system, they are 4*12500, 4*25000 respectively. The size of training and testing datasets indeed have an important effect on the equlization results, and it will be evaluated in our future work. Thank you.

In slide #13, why does the performance of one of the wavelength differ from other wavelengths by 3 dB ? Thank you for your question. For the proposed equalization method, we can not ensure each subcarrier get an equal ACPR gain. By adjusting the parameters of RC, the ACPR gain of subcarrier 4 will be larger, while the ACPR gain of other subcarriers will be smaller.
