Abstract
A method includes receiving, by a first electronic device, a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform over a band channel from a second electronic device, the DFT-s-OFDM waveform including data and reference signals (RS). The method further includes separating, by the first electronic device, the data and the RS using an AI model. The method further includes generating, by the first electronic device, information about the data based on the separated data and RS using the AI model trained to generate information about input bits.
