The application and study of DCA based on measuring CIR in SA system

The same channel can be used in a same cell for smart antenna (SA) system, because of its beam allocation restraining the co-channel interference efficiently. The channel allocation for SA system can fully combine other resources such as frequency, time slot and code, so that it advances the spectrum efficiency largely and achieves high system capacity. In this paper, we make the best of the characteristics of timer, establish multithreading communication simulation model between MS and BS roundly, present an optimum dynamic channel allocation (DCA) strategy based on measuring CIR (MCIR) for the channel composed of the frequency, time slot, code and position beam, and execute the systemic simulation with the performance analysis in Matlab based on the three interfere adaptable DCA rules. Passing the simulation, we obtain some conclusions conforming with theoretical analysis and some valuable parameters.
