noise within the received UWB signal. For this pur-
pose, features are extracted using the DWT. These
descriptors are used as inputs of the LSTM network
which is exploited as a classifier. According to the
extensive experiments carried out on a large dataset.
Promising results are found, which outperform the
performances of the related techniques. For future
work, the employment of CNN to extract features
from the UWB signals can be investigated.
