In this paper we groped for the feasibility about ICI decreasing in precoding OFDM system. First, a model of precoding OFDM system was introduced, then, we present the algorithm of the precoding matrix, Through simulation and analysis, we get the ICI of OFDM system with precoding is reduced, otherwise, the complexity of the receiver does not increase, so(More)
The separate element and common node model is setup to simulate reinforced concrete material at first, which could take fully account of the intensity difference of concrete and rebar. And then a 16-storied frame structure is build with this kind of model. The blasting demoLition process of the structure is simulated. The mechanism of collapse process and(More)
In this study, based on the analysis of the catastrophic risk of rural drinking water, with the representative villages in Ya’an as study objects and setting the four evaluation standards: water quality, water quantity, the Guarantee Probability for water Supply and the Convenience Level of the Access to Water Supply as the basic framework, a Rural Drinking(More)
Performed the size effect of the unit in numerical simulation of blasting demoLition. Considered three elemental sizes, which were 10, 20 and 40 cm. Adopt 40 cm element, the structure was damaged more seriously. This resulted in the bigger error in predicting the demoLition scope. The collapsed time was shorter, and the structural rush distance was farther.(More)
