Cognitive radio (CR) technology with dynamic spectrum management capabilities is widely advocated for utilizing effectively the unused spectrum resources. The main idea behind CR technology is to trigger secondary communications to utilize the unused spectral resources. However, CR technology heavily relies on spectrum sensing techniques which are applied to estimate […]
Novel Filter Bank Based Cooperative Spectrum Sensing under RF Impairments and Channel Fading Beyond 5G Cognitive Radios
The paper proposes a novel filter bank-based cooperative spectrum sensing (FBCSS) technique for cognitive radios beyond 5G, which is robust against radio frequency (RF) impairments and channel fading. The proposed FBCSS technique uses a filter bank to decompose the received signal into subbands and perform local sensing in each subband. […]
