Network Programming And Performance Simulation Of TD-SCDMA Systems

TD-SCDMA is the mobile communication system of the third generation, which our country possess our own intellectual property rights and name brands. As the only system using Time Division Duplex in the 3G system, it has some advantages over systems of Frequency Divsion Duplex. For example, flexibly adjust on the uplink and downlink changing point, make it more suitable for data services; use of intelligent antenna abate the Cell-breathing effect . Because of the differences in the technology, the network expansion planning of TD-SCDMA is different from the other systems of Frequency Division Duplex.This article states the process, methods and simulation of network expansion planning with emphasis on link budget , capability analysis and frequency planning ,proposes the way of analysis and computing formula. Also it proposes the way and analysis of the frequency expansion planning. In the end, it introduces the simulation of network expansion planning of TD-SCDMA and the simulation conditions, and provides the result of simulation and the way of simulation quality assessment...
