AI-based algorithms require a large amount of data to train deep learning (DL) models. In addition, the data used for training can be derived from models and must be matched with data from real scenarios. The term data refers here to the radio channel data, in millimeter wave. The aim of this work is twofold. Firstly, to generate sufficient data at the output of the channel in order to train the DL models. We therefore need to generate new data from the database of measured channels (from ANR projects). Two strategies will be considered. The first will be based on the classic statistical generation of channels used in telecommunications, while the second will consider a very new approach using GAN (generative adversial network), which is well known in the field of image processing. The generated channel data will then be used first for training and then for evaluating the various AI-based channel estimation and spectrum detection algorithms in a more realistic context, corresponding to the measured channel data. The position is open in the framework of the Rgional project IMITECH pilar 4 and also in collaboration with IMT-Atlantique in Brest.
