Although much research has been devoted to the theoretical performance evaluation of cognitive spectrum sharing (CSS) protocols, there are few measurement results available to demonstrate the practical performance of such protocols. In this paper, we have designed and developed a testbed for proof-of-concept demonstration and performance assessment of our proposed CSS protocol. The packet error rate (PER) for both primary and secondary systems are measured to quantify their respective performance. Spectrum access probability for the secondary system is also measured. Measurement results proved that the proposed CSS protocol is able to assist the primary system to achieve a better PER and at the same time allows spectrum access for the secondary system.
