Opportunistic Spatial Orthogonalization and Its Application in Fading Cognitive Radio Networks
Cong Shen, Michael P. Fitz
Opportunistic Spatial Orthogonalization (OSO) is a cognitive radio scheme that allows the existence of secondary users and hence increases the system throughput, even if the primar…
