The Performance Analysis of WCDMA Random Access Technique Based on Self-Similar model

随机接入技术对WCDMA网络数据业务性能优化具有较大影响,文提出基于自相似业务模型的WCDMA接入技术并进行性能分析。仿真结果表明基于自相似业务模型的WCDMA网络数据业务接入性能与分形系数H值、网络负载G等参数有关。文章还提出了基于WCDMA的业务接入自相似均衡协议(TASEP),能明显改善WCDMA网络数据业务的接入性能。

The random access technique has a bigger influence to the performance optimization of WCDMA data traffic. A WCDMA random access technique based on self-similar model and its performance analysis are put forward in this paper. The simulation results indicate that the access performance of the WCDMA data traffic based on self-similar model is attenuated by power law, and related to such parameters as fractal coefficient H and network load G. The WCDMA based traffic access self-similar equalization protocol（TASEP）is also put forward and it can improve the access performance of WCDMA data traffic distinctly.
