Abstract
Deployment of Space-Time Block Code (STBC) over wireless relaying communication
networks has been identified as one of the most promising techniques because of
its potential to support high-performance and high data-rate for wireless communication
technologies of the future. 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.
