Cognitive radio has been proposed to utilize the available spectrum to its optimum level. Sometimes licensed spectrum is not in used because of unavailable user in that area, at that time in place of making it waste, it has been used by unlicensed user and in this way, it is optimally utilized. But the unlicensed user has to make sure that the spectrum band is not in use or in requirement, for this spectrum sensing techniques are used. Energy based detection (EBD) technique is one of the popular technique due to its simplicity and less computation. But due to the presence of noise, sometimes it leads to false detection. In order to improve it, it is studied with different value of threshold and it is found that if threshold is changed with change in SNR then optimum results in terms of probability of detection can be achieved.
