Delay analysis for cognitive radio networks with random access-a fluid queue view
Delay analysis for cognitive radio networks with random access-a fluid queue view FREE-DOWNLOADS Wang, J Zhang… – INFOCOM, 2010 Proceedings …, Abstract—We consider a cognitive radio network where multi- ple secondary users (SUs) contend for spectrum usage, using ran- dom access, over available primary user (PU) channels. Our focus is on SUs’ queueing delay performance, for which […]
balancing technique for downlink beamforming in cognitive radio networks
FREE-DOWNLOAD K Cumanan, L Musavian… – Signal Processing …, 2010 Abstract—We propose a novel signal to interference and noise (SINR) balancing technique for a downlink cognitive radio net- work (CRN) wherein multiple cognitive users (also referred to as secondary users (SUs)) coexist and share the licensed spectrum with the primary .
Demonstration of real-time spectrum sensing for cognitive radio
FREE-DOWNLOAD Z Chen, N Guo… – Communications Letters, research, 2010 – Abstract—The requirement for real-time processing indeed poses challenges on implementing spectrum sensing algorithms. Trade-off between the complexity and the effectiveness of spec- trum sensing algorithms should be taken into consideration. In this paper, a fast
