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 … |
