| Abstract(in English) | Spectrum sensing is an important functionality for secondary systems to ensure that they do not interfere primary systems when they try to access the unused spectrum of the primary systems. Energy detector is one of the possible candidates for spectrum sensing. In this paper, the important practical detection issues of spectrum sensing i. e. effect of quantization and effect of noise uncertainty on the performance of energy detector have been explored. Simulations have been carried out to show that both of these issues have significant effect on the overall performance of the detector. In addition, it has been shown that co-operative sensing helps to reduce those effects to some extent. |
