abstract:
In this work, we propose methods for generating and
manipulating channel impulse responses using normalizing flows.
Using standardised, simplified, analytic models, when no perfect
description of the channel is known, can lead to performance
losses. We are able to show using simulations that our machine
learning methods generate channel impulse responses with forced
features. In addition to that, we show how disentanglement in the
latent space of a normalizing flow can be used for the changing
of certain features. We evaluate our methods using the maximum
mean discrepancy.
