It is called Distributed-STBC (D-STBC) as it uses clients’ nodes as relaying nodes to form a virtual Multiple-Input Multiple-Output (MIMO) channel. However, this requires perfect synchronization among the relaying nodes. Unfortunately, as this is impossible to achieve in real world networks, the structure of the code matrix is compromised causing the channel to appear dispersive. This paper firstly derives a general model of D-STBC systems which will then be used to show the effects of imperfect synchronization on such schemes. Then, it highlights the majority of the schemes used to mitigate the performance degradation due to the asynchronism. In addition, it suggests some schemes that could be considered when conditions of imperfect synchronization exist.
