Abstract

fetched live from OpenAlex

Cognitive Radio Networks (CRNs) is positioned as an appealing autonomous system to enhance spectrum scarcity by dynamic spectrum access and spectrum sharing across wireless networks. To operate at the highest performance level, the allocation and vacation process of primary and secondary users need to be accomplished rapidly. This issue motivates us to propose a fast machine learning-based processing algorithm, referred to as the Arithmetic Shifter-Based Support Vector Machine (ASB-SVM) classifier. The novelty of our proposed scheme is to increase the speed of signal classification by employing shift registers in a two multipliers feature mapping method instead of using multiplication blocks in the SVM classifier. The proposed ASB-SVM design is implemented in Xilinx Virtex-6 XC6VLX240T FPGA. By exploiting spectral features for the classifier, an overall accuracy rate of 98:2% is achieved for green modulated signals in CRNs. Experimental results show that given the feature vector, our proposed system is capable of classifying a blind modulated signal within just 3 ns in the classifier block of a CRN while achieving 30% resource reduction and 45% increase in speed compared to the conventional linear SVM implementation.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
