Error rate analysis of cognitive radio transmissions with imperfect channel sensing
In this paper, error rate performance of cognitive radio transmissions is studied in the presence of imperfect channel sensing decisions. It is assumed that cognitive users first perform channel sensing, albeit with possible ...
Spectrum sensing via restricted neyman-pearson approach in the presence of non-Gaussian noise
In this paper, spectrum sensing in cognitive radio systems is studied for non-Gaussian channels in the presence of prior distribution uncertainty. In most practical cases, some amount of prior information about signals of ...
