Abstract :
This article presents results of the evaluation of the energy detection technique that can be used for the implementation of cognitive radio DSA (Dynamic Spectrum Allocation). The experimental data consists of received signal measurements at geo-positioned points different routes in a urban area, when OFDM signals are transmitted in 3.5 MHz channels with the central frequency of 3,44 GHz. The results are the evaluation of the detection error and the possibility of secondary use of the spectrum along the measurement routes.
