Original Abstract

This paper deals with description of software defined radio test-bed based on USRP2/N200 modules available from ETTUS research. The aim of this test-bed is to develop and test the algorithms for cognitive radio mobile networks. The primary focus is on the spectrum sensing in moving secondary users scenario, adaptation of the radio resource parameters and evaluation of sensitivity to security threats in the mobile cognitive radio networks. Besides the overall architecture description, the paper presents used way to emulate the signals of various communication and broadcasting systems - designed incumbent system simulator and describes the basic implemented blocks - simple OFDM modem, spectrum sensing based on the cyclic prefix correlation and modified method for OFDM subcarrier allocation adaptation.

Keywords
