A mathematical investigation of multi-carrier waveform with AI based matched filter detection

Abstract

Research found that 70% of the spectrum is not being used. Energy, feature detection, and matched filters are just a few of the techniques that have been suggested in the past. A matching filter is used in this study to determine whether a spectrum is free or already in use by the primary user. In this case, if the licensed spectrum for a primary user is not needed, a secondary user may access it. The simulation is carried out by the MATLAB simulation software using the output signals from the OFDM model (proposed model) and NOMA model as inputs. Later in this study, a number of metrics are examined and contrasted with current technology, including probability of detection (PD) and probability of false alarm (PFA).
