Orthogonal Signaling Enabled Cooperative Cognitive Radio Networking,n a cooperative cognitive radio network (CCRN) is proposed and analyzed. Specifically, the cooperation framework in which the SU uses the two-dimensional orthogonal modulation for leveraging two degrees of freedom to relay the PU’s packet and transmit its own data orthogonally in the same time slot

Orthogonally Dull-Polarized Antenna Based Cooperative Cognitive Radio Networking,s (PUs) and secondary users (SUs) for cooperative cognitive radio networking (CCRN). Specifically, we aim to exploit the degrees of freedom provided by orthogonally dual-polarized antennas (ODPAs) to attain an interference-free two-phase cooperation framework. The use of ODPAs enables concurrent tra

The Core Functions of MediaWikiices continues to explode. On the one hand, as a precious natural resource, the amount of most easily explorable radio spectrum for wireless communications is extremely limited. On the other hand, the significant spectrum underutilization resulting from current fixed spectrum allocation polices has
