Original Abstract

This paper presents the verification of the developed MATLAB-based simulator for cooperative spectrum sensing using four different real channel conditions set up between the primary and individual secondary users. Indoor-indoor, indoor–outdoor, outdoor-indoor and outdoor-outdoor are taken into consideration. In the transmitter side two types of signals are generated – the analogue FM signal and the digital 8PSK signal. Then these signals are processed using the Universal Software Radio Peripheral (USRP) devices. One of them is defined as a transmitter and another two for the receiver side. Two types of detectors – the energy detector and the Kolmogorov-Smirnov-based statistical detector have been implemented at the receiver for signal sensing evaluation. This system is built to insure the effectiveness of the simulator and cooperative sensing approach not only in simulated channels but also in real ones. Therefore, the achieved results are compared with simulation ones.
