Abstract :
In this paper, a new cooperative scheme for signal detection is proposed. Unlike previous works in the field, the new scheme does not require the knowledge of the noise statistics and is related to the behavior of the largest and smallest eigenvalue of channel matrices. Simulations show that the new algorithm is effective, outperforming classical energy detected techniques.
