Spectrum access approach and power allocation scheme are important techniques in cognitive radio(CR) system,which not only affect communication performance of C
With the rapid development of mobile Internet, people pay increasing attention to the wireless network security problem. But due to the specificity of the wirel
The fact that the security facilities within a system are closely coupled and the security facilities between systems are unconnected results in an isolated pro
Large-scale array aided beamforming improves the spectral efficiency(SE) as a benefit of high angular resolution.When dual-beam downlink beamforming is applied
In this paper, a generalized three-dimensional(3D) scattering channel model for macrocellular land mobile environments is considered. This model simultaneously
