Cooperative Spectrum Sensing (CSS) was proposed as one solution to overcome uncertainty noises in primary signal detection. It increases capability of primary signal detection and accuracy. This paper investigates the performance of decentralized CSS model with limited sensing capability in Cognitive Radio (CR) system. Simulation considers multiple Secondary Users (SUs) sense license channel and distributes ...

In this paper, the authors deal with partial discharge induced electromagnetic wave investigation on three-phase GIS using UHF method and the application of single-phase Partial Discharge Monitoring device (PDM) on three-phase Gas Insulated Switchgear (GIS). The PD source is a protrusion at different positions on the conductor or on the tank. Frequency and phase spectrums ...

In this paper, the authors introduce a specific architecture including an infrastructural IP for functional verification and diagnostics, which is suitable for functional core-based testing of an MPEG4 SoC. Their advanced MPEG4 SoC results in a high complexity SoC (System-on-Chip) with limited physical access to many different functional cores. The proposed test method provides direct ...
