A near-optimal LLR based cooperative spectrum sensing scheme for CRAHNs
Alvi, Sheeraz A.; Younis, Muhammad S.; Imran, Muhammad; Amin, Fazal-e-; Guizani, Mohsen ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)In Cognitive Radio Ad Hoc Networks (CRAHNs), cooperative spectrum sensing schemes exploit spatial diversity of the Secondary Users (SUs), to reliably detect an unoccupied licensed spectrum. Soft energy combining schemes ... -
Automatic Modulation Classification for Low SNR Digital Signal in Frequency-Selective Fading Environments
Wallayt, Waqas; Younis, Muhammad S.; Imran, Muhammad; Shoaib, Muhammad; Guizani, Mohsen ( Kluwer Academic Publishers , 2015 , Article)In this research, a classifier is proposed for automatic modulation classification of some common modulation schemes, i.e., BPSK, QPSK, 8-PSK and 16-QAM. Our proposed classifier considers multipath fading effects on the ...
