B3G系统的频谱需求分析

Analysis of Spectrum Requirements for B3G Systems

B3G网络具有更高的复杂性和业务多样性,对频谱需求分析方法提出了更高的要求,ITU-RWP8F工作组正在开展对B3G的频谱需求分析。本文介绍了B3G频谱需求分析的通用流程,详细说明了其中的系统容量算法;并对频谱需求分析所需的电路交换业务资源占用度量方法进行了研究。

B3G networks will be more complex and will provide more diverse services than the current 3G systems. These also induce higher requirements to the analysis and estimation of spectrum requirements for B3G systems. ITU-R WPSF is developing a methodology for the analysis of spectrum requirements for B3G systems. This paper introduces the general procedures of B3G spectrum requirement analysis in details, especially the algorithms for system capacity requirement calculation. This paper also studies and compares three different methods to measure the resources used by each circuit switched service, which is to be determined in spectrum requirements analysis.
