Abstract EN
A signal detection scheme is proposed for two-way relaying network (TWRN) using distributed differential space-time coding (DDSTC) under imperfect synchronization.
Unlike most of existing work, which assumed perfect synchronization and channel state information (CSI) at all nodes, a more realistic scenario is investigated here by considering the signals transmitted from the two source nodes arriving at the relay not exactly at the same time due to the distributed nature of the nodes, and no CSI is available at any node.
The proposed signal detection scheme is then demonstrated to remove the imperfect synchronization effect significantly through simulation results.
Furthermore, pairwise error probability (PEP) of the asynchronous TWRN is analyzed and derived for both source nodes.
Based on the simplified PEP expression, an optimum power allocation (OPA) scheme is then determined to further improve the whole system performance, when neither the source nor the relay has any knowledge of the CSI.
