碩士 === 國防管理學院 === 國防資訊研究所 === 92 === Space-time block coding is one of the most significant technical breakthroughs in modern communications. The technology figures prominently on the list of recent technical advances with a chance of resolving the bottleneck of traffic capacity in future Internet-intensive wireless networks. This is because it can used channel capacity, bandwidth efficiently , noise mitigation under non increase of the complexity. This paper propose in coding or increase some of the time and space dimension to provide more coding gain under the STBC design in the sensor networks, to adapted in the different fading environment. we can used different matrix in order to received signals with low BER. It also can get balance between system complexity and coded gain.
