This paper focuses on the quantization of soft decision based cooperative spectrum sensing (CSS). The soft data fusion CSS schemes in previous research works provide considerable enhancement in the probability of detection, but at the expense of increased bandwidth required for transmitting the sensing measurements to the Fusion Center (FC). In this paper, Maximum likelihood Estimation (MLE) statistics...
A data-fused fault diagnosis method based on wavelet packet decomposition of voltages of test nodes and current signals of the terminals stimulated is proposed in the paper. For the faults difficult to detect merely from voltages of test nodes, the current signals of the terminals which contain sufficient information with various faults are fused with the sampled node voltages of the circuit stimulated...
