Towards Optimal Constellation Design for Digital Over-the-Air Computation
Saeed Razavikia, Deniz Gündüz, Carlo Fischione
Over-the-air computation (OAC) has emerged as a key technique for efficient function computation over multiple-access channels (MACs) by exploiting the waveform superposition prope…
