摘要
介绍了在TD-SCDMA快速下行分组接入技术(TD-HSDPA)系统中链路级仿真与系统级仿真之间的映射方法,主要探讨了联合检测增益在链路级获取和系统级应用的两个方面。重点阐述了如何根据链路级仿真得到联合检测的干扰消除因子的统计特性,并将其映射到系统级仿真的SINR模型中的策略。对比于传统仿真方法论中所采用的固定干扰消除因子的策略,文章所设计的映射策略具有更高的准确性和可靠性,并能够更好地适应实时的信道环境。
An effective mapping approach between link-level simulation and systemlevel simulation in TD-HSDPA （TD-SCDMA High Speed Downlink Packet Access） is introduced in this paper. A novel scheme that expounds how to obtain the gain in Joint-Detection （JD） on linklevel simulation and the applications on systemlevel simulation has been illustrated. Meanwhile, how to get the statistical properties of interference cancellation factor [5 in JD on link-level simulation and strategy that mapping to SINR model of the system-level simulation are expatiated in details. Compared with the conventional simulation methodology using the fixed I3, the proposed mapping strategy achieves higher accuracy and reliability, which can make the simula- tion results approach the actual environment better.
