Signal Detection for QPSK Based Cognitive Radio Systems using Support Vector Machines

Cognitive radio based network enables oppor- tunistic dynamic spectrum access by sensing, adopting and utilizing the unused portion of licensed spectrum bands. Cognitive radio is intelligent enough to adapt the commu- nication parameters of the unused licensed spectrum. Spec- trum sensing is one of the most important tasks of the cogni- tive radio cycle. In this paper, the auto-correlation function kernel based Support Vector Machine (SVM)...
