Some question about scaling_factor

[qiangdadi]

I have some questions about the scaling_factor in diff_rt. Why you want to use scaling_factor and why you get scaling_factor like this

scaling_factor.assign(delta*scaling_factor + (1-delta)*mse_power_scaling_factor(h_rt, h_meas))

I know this is some question about diff_rt but I didn't find any place to draw a question.

Hi @qiangdadi,

Did you have a look at the corresponding paper? It is explained there.
The problem is that our dataset has a common but unknown scaling factor.
We compute this factor iteratively via a moving average. This is the line you have pasted.
