<P>Spectrum sensing is one of the most important parts of the cognitive radio system. In order to detect the primary user signal, the robust sensing method is required. In this paper, we propose a combination of the energy detection method and the autocorrelation-based detection method with a cascaded architecture to improve the probability of detection. Energy detection involves lower complexity and energy consumption, but it is unreliable at low signal-to-noise ratios (SNRs). Orthogonal frequency division multiplexing signal property is used by an autocorrelation-based detector, which involves more complexity and is more robust at low SNRs. We build the cascaded design of both energy detection and autocorrelation-based detection to take advantage of each technique. The performance of a cascaded detector is then presented. It is shown that the probability of detection of the cascaded design is always better than the probability of detection of a single detector. The design of the cascaded detector has been implemented which does not require additional sensing time. The complexity and utilization of each detector design is then presented to show the efficiency of the proposed design.</P>

The Importance of Employees Redistribution in South Sulawesi Higher Educations, Indonesia
SALEH, Haeruddin,HAMKA, Husain,MAIDIN, Rusdi,MANDA, Darmawati Korea Distribution Science Association 2022 유통과학연구 Vol.20 No.2
Purpose: This research aims to provide solutions for human resource problems in public educational institutions to improve employee performance. Research design, data, and methods: The study used a quantitative approach with a survey method. Data were obtained through questionnaires and documentation. Meanwhile, the model used path analysis using Analysis Moment Structure (AMOS) software. Results: Results showed that there was a significant relationship between locus of control and redistribution variables on employee empowerment as well as on employee performance. This result implied that good management through the locus of control and employee redistribution in public organizations could be better to serve the community and organizations. Public change to be superior and demanded by the community to make it a good place to learn. Employees' good behavior and increasing competence can satisfy users of educational and sustainable institutions. Conclusion: To sum up, research on management development of locus of control and employee redistribution is needed to make public organizations, especially those engaged in education. This study provides academic implications by revealing that the locus of control factor and employee redistribution in public organizations are needed to improve institutional services.
