The Test And Analysis Of TD-SCDMA Network Performance With High Load

As one of the 3rd Generation standards in the world, TD-SCDMA has been widely used in China.And there have been a rapid growth in TD users with the strong push by China Mobile. The co-channel interference is the common problem faced by the 3G wireless system; because TD-SCDMA has small spread spectrum gain and doesn't support soft-switching, the co-channel interference issues will have a more prominent effect on the network's capacity and quality with the increasing in the number of users.For testing and analysising TD-SCDMA network performance with high load,this paper design a complete set of test methods according to the TD-SCDMA network features,and gives a theoretical analysis, simulation analysis, a single station and the local area actual loading method,gets the loading power conversion relationship under the scene of Shaoxing's network between simulating load and real users'load,and then analysises the network's performance and optimization-technology on the condition of the 55% users' load by the way of the time slots'power uniform load in the whole network and proposes optimization methods for TD-SCDMA network.
