In the frame of the evolution of wireless networks, in this talk we will focus on non-coherent communications. Combined with massive MIMO, non-coherent schemes can overcome the channel estimation bottleneck and provide high throughput communications in environments with high variability (vehicular, high speed trains). We will show how artificial intelligence (AI) is currently being used to improve the waveforms that are employed for transmission in such systems, allowing to achieve the spatial multiplexing of several users with a feasible number of antennas. Other challenges of this kind of communications where the use of AI can be beneficial will be also discussed.
