Multi-hop could bring advantages such as low up-front cost, easy network maintenance, robustness, reliable service coverage etc for the next generation wireless networking. However, to be more available, wireless multi-hop network confront with much more challenge. First of all, the capacity of multi-hop is an open issue, for the optimal schedule of the distributed node is still illegible. Derived...
For a two hop cooperative relay communication system, the first hop mainly gets the diversity gain, and the second hop gets the cooperative gain. While HARQ gets the time diversity gain, space-time or the others coding has the chance to get a tradeoff between diversity gain and multiplex gain. It is significant to combine the HARQ and STBC in a cooperative MIMO system that formed by a set of cooperative...
A method based on fractal geometry is suggested to simulate the porous structure of calcined limestone, in which a model similar to the Menger sponge is employed for the porous calcine. The bulk fractal dimension is calculated on the basis of the experimentally obtained poresize distribution density. The effects of various factors (such as particle size, calcination temperature and environment,...
