To Improve the Probability of Detection in Spectrum Sensing by Using Equal Gain Combining Technique
Development of smart spectrum sensing techniques is the most important task in the design of a cognitive radio system, which uses the available spectrum efficiently. The Energy Detection (ED) and covariance absolute value (CAV) methods do not require any information about the signals, channel, and noise power. So these techniques are known as blind spectrum sensing techniques. This paper mainly focusing on equal gain combining technique. This technique was applied on both Energy Detection (ED) and covariance absolute value (CAV). By using this technique at low Signal to noise ratio (SNR) this system can improve the probability of detection.
