Abstract:

The hybrid transmission scene involving both broadcasting link and relay link is considerd with channel estimation error. The bit error rate performance of amplifyandforward based transmission in reporting sensing data is analyzed. By deriving effective signal to noise ratio at the common receiver, the approximate expressions for average bit error rate is obtained. Simulations are further provided to confirm the analytical results.

Key words: cognitive radio, cooperative diversity, amplifyandforward relay;channel estimation error
