E-mail: 1yawadasemba2013@, 2ajw626@ ABSTRACT The recent and rapid evolution of wireless technologies has led to a high demand in terms of resources. To solve this prob-lem the idea of cognitive radio has been introduced to facilitate a good spectrum management and efficient use of the spectrum. In this article, a method for the detection of the spectrum with the purpose of detecting the presence of bands of unoccupied frequencies is proposed. The method used is the matched filter. The performance was assessed by using the MATLAB based on the AWGN channel.

This evolution has been accompa-nied by an increased demand in radio resources. However, the resources accessible by the existing technologies do not allow them to meet the demand. In order to overcome the scarcity of frequencies, new concepts of sharing of resources, as the dynamic allocation of a radio channel has a new communication has been developed. Nevertheless, the last two decades have seen a veritable explosion of telecommunications services. From mobile telephony to wireless transmissions of data, the quantity of general public services increases and the scarcity of frequencies is more than ever aggravated. In 2002, the Federal .
