Conventional cooperative sensing scheme is a typical solution in cognitive radios for sensing and spectrum access under fading channel conditions and hidden node scenarios. The drawbacks of this scheme are its requirement of additional resources as well as the time delays involved in it. In this paper, we propose a mechanism for a single band structure, in which the two communicating secondary users...
In the secondary radio limited access (SR-LA) scheme, the secondary radio (SR) is limited to access parts of the frequency bins in order to obtain a tradeoff between the SR dropped probability and SR blocked probability. In this paper, we present the complete expressions of the balance equation and the blocked probability for the SR-LA scheme. Simulations and numerical analysis are conducted to verify...
