The Planning And Realization Of Radio Network On TD-SCDMA

With the development of TD-SCDMA mobile telecommunications techonology,the key technology smoothly resolved. TD-SCDMA terminal equipment such as basestations and wireless controller business, in order to improve the system capacity, basestations to expand coverage to ensure that the quality of signal transmission networkplanning is becoming increasingly important. As for the future of TD-SCDMA networkoperators. How cost-effective to build a TD-SCDMA cell net, is a guarantee of highquality and low cost network iperators are concerned about. Network planningpurposes,generally speaking, it is in support of a variety of multimedia services andQoS to meet certain conditions, have a good network capacity to meet certainrequirements of wireless coverage, by adjusting capacity,coverage, Links between thebalance between providing the best quality of service.Asfor the future of the TD-SCDMA network operators, Due to adopt TD-SCDMAis the only ITU support TDM(TDD), CDMA(CDMA)system.Both WCDMA andCDMA2000and frequency division multiplexing (FDD) technology compared to theCDMA system than using the time division multiplexing, multi-user detection uplink,uplink time synchronization and advanced smart antenna technology TD-SCDMAnetwork makes more flexible and comples. FDD traditional2G and3G CDMA systemsuse planning methods can not meet the demand. TD-SCDMA system must step in theplanning for deep study TD-SCDMA conforms to the characteristics of the new plan.This paper introduce the history of the development of mobile communicationssystems, and then analysis of the composition and characteristics of the third-generationmobile communication technology such as WCDMA and CDMA2000. Then, itanalyzed characteristics of TD-SCDMA technology and the characteristics of itsnetwork planning. Next, a detailed discussion of the core issues: Network Planning LinkBudget, wireless communication model and wireless capacity analysis. In the discussionof these issues through the inrotduction of3G networks now planning methods: MonteCarlo simulation method commonly used in simulation. In-depth presentations andanalysis of the Monte Carlo simulation.In-depth presentations and analysis of the MonteCarlo simulation method based on the TD-SCDMA network simulation and research.
