Abstract


This paper analyzed the frequency spectrum in the ISM band and identified spectrum holes to be used for transmission by the secondary users. By measuring the spectrum using Universal Software Radio Peripheral (USRP) devices, this work employed a realistic approach. Thus, the spectrum holes in the frequency spectrum had distinguished by using an energy detection technique. In the energy detection technique, the threshold energy level is set and then compare with the energy detector output to identify the existence of the primary user (PU). The result indicates that 0.61% of spectrum holes have been detected in the 2.43 GHz to 2.44 GHz range. This range is sufficient for home appliances, RF peripherals and Bluetooth devices.
