Modulation recognition algorithms have recently received a great deal of attention in academia and industry. In addition to their application in the military field, these algorithms found civilian use in reconfigurable systems, such as cognitive radios. Most previously existing algorithms are focused on recognition of a single modulation. However, a multiple-input multiple-output two-way relaying...
In this paper, we propose a low-complexity sensing algorithm based on the generalized likelihood ratio test that satisfy the complexity-performance compromise. The proposed algorithm can significantly reduce the complexity computation of the eigenvalues and enhance outstandingly the detection performance compared to the existing GLRT algorithm. Besides, the cooperative spectrum sensing has proved...
In this letter, we investigate the performance of modulation identification based on pattern recognition approach using the decision tree (J48) classifier, for multiple-input multiple-output (MIMO) relaying broadcast channels with direct link (source-to-destination). The proposed system identifies the modulation type and order among different M-ary shift-keying linear modulations used by broadband...
