HSDPA技术与WCDMA移动通信系统共存干扰分析
首发时间:2008-07-18
摘要:HSDPA通过自适应编码等关键技术大大提高了下行数据传输速率,因此成为WCDMA系统的演进方向,本文主要阐述HSDPA技术引入WCDMA系统后,与原系统共存干扰分析,首先通过理论分析得出两者之间存在干扰,然后通过计算机仿真得出符合理论分析的结果,同时通过仿真结果,给出一些减小干扰的建议。

Study on Co-existence of HSDPA and WCDMA Mobile System
Abstract:HSDPA can increase downlink data rate by using Adaptive Modulation and Coding, so it has been the evolution of WCDMA system. This paper presents interferences between HSDPA and WCDMA. Firstly, the analysis of interferences between HSDPA and WCDMA is introduced. Secondly, simulation results are shown for proving the former analysis. Finally some advices to decrease the interferences between HSDPA and WCDMA are given.
Keywords: WCDMA, HSDPA, Interferences Analysis
