Q. Why does it utilize dithering noise?
A. At high SNR with one-bit ADCs, it is hard to get enough statistics with the reasonable training length because it rarely shows sign changes in a short frame. Dithering noise perturbs the received signal to get the desired statistics. After that, the effect of dithering noise will be removed because the BS knows what it is.
Q. Is dithering noise used during the data transmission phase?
A. No. Dithering noise helps to get enough statistics during the training phase, but it is no longer used after the BS gets an initial guess of transition probability.
Q. What is the meaning of the dithering variance?
A. This is the amount of perturbation, so we've increased it proportional to SNR. Designing an optimal dithering variance is our future work.
