| The global call for proposals of 4G has concluded in October 2009.ITU received six proposals covering two categories of technology solutions, LTE-ADVANCED and 802.16m. LTE-ADVANCED has become the most competitive candidate for 4G technology. In order to verify the proposed technology, simulations are indispensable.According to the requirements of 3GPP to 4G wireless communication system's performance, BUPTICN designed and built a LTE-ADVANCED wireless communication system simulation platform.Simulation platform includes geographic topology, Wrap-around, big/small-scale fading, interference calculation, Adaptive Modulation and Coding, HARQ,packet scheduling and other functional modules.The simulation platform has important implications for the LTE-ADVANCED studyThe main research work is to design and investigate a semi-static LTE system level simulator. The primary accomplishments are determination of the whole system framework, building several important modules, debugging entire simulator, and data collection and comparison.It ends with the suggestion and expecting on the future research and application of this simulator.This work firstly introduces the development situation and key technologies of the Long Term Evolution (LTE).Secondly, the work describes circular flows, and a few important modules in this simulator. Thirdly, the work introduces the design thinking, related data structures and parameter configuration of this simulator. Finally, the work gives some deep analysis on the simulator's results. |
