This work addresses the problem of estimating the interference temperature in cognitive radio systems. The proposed technique exploits higher order moments of the received signal to achieve accurate estimation of the noise and signal power. Then, the noise power is used for the evaluation of the interference temperature. Performance analysis has been carried out in comparison with the conventional energy detection method. The numerical results, obtained from wide simulation trials, have evidenced the efficiency of our method for estimating the interference temperature in cognitive radio communications.
