摘要： 提出了WCDMA系统中一种利用信道估计相位变化的统计信息来估计最大多普勒频移的自适应方法,并在分析相对误差的基础上给出了校正公式.仿真结果表明该方法简便易行,精度高,并且不受功率控制等因素的影响,在3G标准支持的宽广的多普勒频率范围内都能获得良好的估计效果.

Abstract: In this paper, a scheme that adaptively estimates one of the most important channel parameters——maximum Doppler frequency fD is proposed for WCDMA systems. The scheme uses phase variations of received pilot signals, strongly related with fD in a fading environment. The simulation results show that the proposed scheme is very simple, showing good performance over wide Doppler frequency range supported by 3G standard.

Key words: WCDMA, phase variation, maximum doppler frequency
