Hybrid Matched Filter Detection Spectrum Sensing [PDF]
IEEE Access, 2021 The radio frequency spectrum is getting more congested day by day due to the growth of wireless devices, applications, and the arrival of fifth generation (5G) mobile communications. This happens because the radio spectrum is a natural resource that has a restricted existence. Access to all devices can be granted, but in a more efficient way.
