A major challenge for cooperative communication in distributed networks is to coordinate relay transmissions without introducing too much overhead. Targeting a clustered network, we propose a novel cooperative communication scheme including channel quality based relay selection and distributed space-time code allocation in this paper. Both analysis and simulations are carried out to investigate the...
Cooperative spectrum sensing improves detection performance over fading and shadowing channels by using multiple cognitive radio (CR) users. Compared with local spectrum sensing with individual CR user, it can either reduce sensitivity requirements for each CR user or shorten the overall sensing duration. These advantages are from spatial diversity when all cooperative users sense a common primary...
