Abstract

In this paper, we have discussed the effects of channel interference and evaluated the signal-to-interference plus noise ratio (SINR) for the cognitive radio (CR) network. The cognitive radio is a novel concept of reusing licensed spectrum with unlicensed manner. The most challenging part is the introduction of cognitive radio in the primary user spectrum without causing interference to it. The SINR is very significant parameters for evaluation of the performance in a wireless network. Different users have different SINR requirement, so it is very important that the SINR of a particular user is within a certain acceptable range. The calculated SINR is more precise by considering the uplink and down link frequencies.
