Abstract

Abstract

The Channel State Information (CSI) is not taken into consideration in Co-ordinate Interleaved Distributed Space-Time Code (CIDSTC) for two-antenna-relays networks. For this issue, CIDSTC based on Phase Rotation (PR-CIDSTC) is proposed, in which relays rotate their transmitted signals with certain angles. Since these angles are designed to minimize Pair Error Probability (PEP), the performance is enhanced. Simulation demonstrates that the proposed scheme provides a 1.5 dB gain at Bit Error Rate (BER) of10-5 over PR-CIDSTC with only 2 bit feedback amount.
