In this paper, optimal multiple channels cooperative spectrum sensing setting in non-identical environment is investigated. In previous works on cooperative sensing, the secondary users are assumed to have the same detection threshold and the noise received is assumed to be independent identically distributed random variable. Thus researchers often assume that identical sensing time is assigned to...
In this paper, joint optimization of throughput and error rate via cooperative spectrum sensing in cognitive radio networks is investigated. An optimization problem is formulated, which aims to maximize the average achievable throughput of cooperating cognitive users while keeping the error rate at a lower level. This is a multi-variable nonconvex optimization problem. Instead of solving it directly,...
