摘要： 研究了cdma2000 1x反向链路的Rake接收机的原理,建立了cdma2000 1x的定点仿真平台,用COSSAP软件对此进行了仿真,并与浮点仿真结果作了比较,着重研究了定点化对于Rake接收机和Viterbi译码的影响.

关键词: cdma2000, 反向链路, 定点仿真, Rake接收机

Abstract: In this paper, we discuss the principle of the Rake receiver for cdma2000 1x reverse link. The fixed-point simulation platform is also developed by COSSAP. We compare the simulation performance between fixed-point and float-point and study the degradation due to the finite word length implementation of the Rake receiver and viterbi decoder with various A/D quantizers for a cdma2000 1x reverse link.

Key words: cdma2000 1x, reverse link, Rake receiver, fixed-point simulation
