Development And Research Of Wireless Communication System Interfering Co-Existence Platform

With the development of mobile communication technology, various wireless communication system standards emerge. The rare of frequency resource makes multiple coexisting wireless communication system work on the adjacent frequency. The un-ideal characteristic of the receiver filter leads to inter-system interference inevitably in the multiple systems coexisting scenery. As a result, it is important to research and development the simulation platform to simulate the interference of different systems for spectral planning and improvement of the operating quality.One key point in the research and development of the wireless communication system interference coexisting platform is how to solve the difference of different mobile communication system. For example, the 3G mobile communication system contains four standards: TD-SCDMA, CDMA2000, WCDMA, Wimax. If we build a simulation platform for every two different systems, there will be many simulation platforms, which cost many resource and is useless for further research. So it is of great importance to design a general, compatible interference coexisting simulation platform to satisfy the need of interference coexisting research and also build a solid base for research on further systems.In essay researched on the main key technologies of the mobile communication system and system-level static simulation and at last proposed a scalable platform designing solution,which can be used for the research of co-existence of interference of GSM, Tetra, PHS, TD-SCDMA, WCDMA, cdma2000 and so on, and do research about the coexistence interference between the single basestation system and the TD-SCDMA systems.Firstly the essay briefly involves the current situation about the research of co-existence. Then the key techniques of TDD and single basestation system, such as duplex mode, power control are introduced in details.Then, the paper analyzes the interference of the single link between between the single basestation system and TD-SCDMA system, then,two method of coexistence research that are MonteCarlo simulation and certainty analysis are introduced in details.And, the paper described the simulation processes, platform architecture and user interface of the simulation platform, introduced the important modules of the platform, algorithms and implementation in detail.Finally, in order to verify the accuracy of the platform, the paper gives the interference coexistence simulation results between the single basestation system and TD-SCDMA and the coexistence advice。...
