  • Multitaper spectrum : A promising method in spectrum sensing cognitive radio
  • 2010
  • Konferensbidrag (refereegranskat)abstract
    • Cognitive radio (CR) has been proposed as a promising and effective technology to improve radio spectrum utilization. The primary objective of the CR is to handle the non-interference rules with any primary users (PUs). Highly sensitive and optimal spectrum sensing detectors are required in order to avoid harmful interference to PUs. Multitaper spectrum seems to be the most appealing one for spectrum sensing CR because of its accurate identification and estimation and low computational complexity. Mulitaper uses small set of tapers and multiple orthogonal prototype filters to reduce the variance. The Fourier transform of a Slepian sequence, originally known as discrete prolate spheroidal sequences (DPSS), gives maximum energy density inside a given bandwidth and less spectral leakage with better specifications has been investigated in this paper and shows that no other window in signal processing can satisfy this property

  • Tidskriftsartikel (refereegranskat)abstract
    • This paper examines the relationship of training, job satisfaction, and corporate brand image with employees working performance at British American Tobacco, Dhaka. A significant relationship exists between training and employees’ performance at BAT Dhaka in Bangladesh. To produce better work efforts, it is important to note that job satisfaction influences satisfactory performance output. It is found that brand image psychologically influences and motivates employees and is strongly related to employees working effort. About 100 questionnaires were distributed among the respondents of BAT Dhaka and data were analyzed. Correlation analysis and stepwise regression analysis were performed for testing hypotheses. The research showed that relationships exist between Training, Brand Image, and Job satisfaction among employees working performance.
