摘　　要：接收机的设备性能取值是链路预算中的一个重要参数,其指标的差异直接影响无线网络的性能。在CDMA系统中,特别是以数据业务为特色的3G系统中,接收机一般以Eb/No的取值为其解调门限。本文首先解析了CDMA系统中Eb/No的具体含义,以明确此参数对无线性能的影响和作用,此外,针对3G各制式规范以及文献中出现的类似指标也进行了阐述,方便读者理解和比较。The performance of receiver is a key parameter of wireless networkts link budget. In CDMA system, especially in packet data service of 3G system,the required value of Eb/No is commonly used to judge the capability of receiver. In this paper, we firstly explain Eb/No in CDMA system and point its influence on wireless network. Moreover, to offer reader a comprehensive understanding and comparison,we also concisely discuss similar parameters in 3GPP,3GPP2 and other references.
