| Abstract | Cognitive radios need to be able to detect multiple wideband interferers of unknown statistics from a single received sample vector. This paper establishes the received signal statistics to enable specification of the hypothesis test that must be evaluated to perform detection of such signals. Hidden Markov modelling is proposed for evaluation of the required likelihood ratio tests. Detection performance is established using computer simulation. It is concluded that detection of multiple wideband interferers under the assumed conditions should be performed with caution, depending on the desired application. |
