Channel State Information, decentralized distributed Space Time Block Coding, power allocation, outage and link failure probabilities.


Two ad-hoc, power allocation strategies for a decentralized distributed Space Time Block Coding (Dis-STBC) system is proposed in this paper where knowledge about the Channel State Information (CSI) is not available at the transmitter. The first is an open-loop strategy which requires no control signaling; the second is a feedback-assisted strategy which requires some control signaling, but which can achieve better power-efficiency. Focusing on a particular decentralized Dis-STBC scheme, the asymptotic outage probability is derived and the power-efficiency advantages of the proposed strategies over a uniform-power strategy are illustrated by evaluating the outage and link failure probabilities.
