摘要：
Exploiting the source-to-relay channel phase information at the relays can increase the rate upper-bound of distributed orthogonal space-time block codes (STBC) from 2/K to 1/2, where K is the number of relays. This technique is known as distributed orthogonal space-time block codes with channel phase information (DOSTBC-CPI). However, the decoding delay of existing DOSTBC-CPIs is not optimal. Therefore, based on the rate of 1/2 balanced complex orthogonal design (COD), an algorithm is provided to construct a maximal rate DOSTBC-CPI with only half the decoding delay of existing DOSTBC-CPI. Simulation results show that the proposed method exhibits lower symbol error rate than the existing DOSTBC-CPIs. © 2016, Editorial Department of Transactions of NUAA. All right reserved.
