Distributed Linear Dispersion Space-Time Code

In this paper, a new distributed space-time code incorporating linear dispersion propriety used in cooperative diversity system is introduced. After a CRC detection, each cooperative node applies distinctive transmit method according to its CRC result. Based on PEP upper bound analysis, we deduce optimal power allocation for this system. Besides, theory analysis demonstrates that our proposed Distributed Space-Time code can almost achieve full diversity. Simulations further verify our theory deduction and demonstrate an obvious improvement over some other Distributed Space-Time code under the same circumstance.
