Blockchain-enabled cooperative spectrum sensing in 5G and B5G cognitive radio via massive multiple-input multiple-output nonorthogonal multiple access

Autor: D. Balakumar, S. Nandakumar

Publikováno v: Results in Engineering, Vol 24, Iss , Pp 102840- (2024)

One of the greatest ways to guarantee that networks designed for fifth generation (5G) and beyond reach the required levels of spectrum efficiency (SE) is through nonorthogonal multiple access (NOMA). This work presents two new blockchain-based techn

Cognitive Radio Spectrum Sensing-Based QAM Technique Using Blockchain

Autor: D. Balakumar, S. Nandakumar

Publikováno v: International Journal of Distributed Sensor Networks, Vol 2023 (2023)

Cognitive radio (CR) is a novel concept developed to solve concerns such as spectrum underutilization and scarcity. Spectrum detection methods are employed in the blockchain-based CR to make optimum use of the spectrum reserves. In this paper, an att
