GENERATES RAIN ATTENUATION SIGNAL for a given noise percent
*alpha* and quantization step *delta*
Inputs:
savefile - string. File path to save the RSL data.
alpha - scalar. Noise percentage.
delta - scalar. Quantization step.
model_type - string. Attenuation model type. 'theoretical' is set by default.
Avaiable models: 'theoretical', 'empirical'
Output:
None
