Based on conventional single-threshold energy detection algorithm, we put forward a double-threshold version in cognitive radio system, and then, we analyze the detection probability, false alarm probability, miss probability and their relationships. For further research, we define two parameters for performance evaluation: the probability of collision between the cognitive user and the primary user, and the probability of spectrum unavailable to the cognitive user. Comparing to the single… CONTINUE READING
