摘要 增强高速分组接入(HSPA+)是一项新的B3G技术,其目的是为了对现有的高速分组接入系统(HSPA)进行平滑升级,从而在尽量保护现有系统投资基础上满足用户对更高数据速率的应用需求。在介绍3GPP标准中提出的HSPA+基础上,重点讨论了HSPA+系统物理层新引入的多天线收发(MIMO)和高阶调制技术,讨论了这些技术的具体实现方法以及对原HSPA系统带来的性能提升。通过仿真结果,可以看到这些性能上的提升使HSPA+系统可以在5 MHz带宽上获得与3GPP长期演进系统(LTE)相近的性能。 High speed packet access evolution (HSPA + ) is a B3G (Beyond the third generation) system which aims at improving the current HSPA with less cost of equipment upgrading. Based on the introduction of HSPA + in 3CPP, this paper discusses the MIMO and higher order modulation which are used for improving the performance of the current HSPA system. Simulation result shows that these improvements are comparable to those of long-term evolution of UMTS terrestrial radio access network in a 5 MHz deployment,
