Dynamic spectrum access to unused licensed spectrum has been proposed as solution to the spectrum scarcity problem. Reliable detection of any primary user signal is crucial for the required interference-free operation. It has been shown that cooperative sensing has the potential to alleviate propagation effects such as fast fading or shadowing and thus to improve sensing reliability. However, there is lack of practical studies confirming the theoretical results. In this paper we present our… CONTINUE READING
