Secondary users in cognitive radio networks need to learn the statistics of spectrum in order to achieve efficient communications. Due to the spatial correlation, the efficiency of learning is improved by letting secondary users collaborate and exchange information. Due to the similarity between the collaborative learning in cognitive radio networks and the recommendation systems of electronic commerce like Amazon, the technique of collaborative filtering is applied. Prediction oriented and… CONTINUE READING
