Abstract:
Cyclic Delay Diversity (CDD) method was introduced to cooperative communications for improving the system diversity performance. Since the CDD with fixed cycle delay cannot obtain the optimal system performance in all situations, this paper presents a full-rate distributed space-time-frequency codes scheme in the full-rate cooperative communication model by taking advantages of Randomized Cyclic Delay Diversity (RCDD) method and Linear Constellation Precoding (LCP) technology. The proposed scheme is more practical and has the advantage of low detection complexity. Compared with the full-rate cooperative communication scheme with Fixed Cyclic Delay Diversity (FCDD), the proposed scheme can achieve Better Bit Error Rate (BER) performance in the case of large number of subcarriers.
