WCDMA系统小区搜索过程中频偏估计的研究

he study of frequency estimation in the progress of cell search in WCDMA system

中文摘要英文摘要

针对WCDMA系统初始小区搜索过程中由于廉价的晶体振荡器引起的频率偏移,本文进行了深入的研究。主要介绍一种基于FFT和在频域内二次插值的频偏估计算法,之后进行仿真、深入分析仿真曲线,结果表明该算法不仅可以提高频偏估计的精度,而且频偏估计值具有很高的可靠性和良好的稳定性,该算法是可行的。

In WCDMA system, Frequency error introduced by the cheap oscillator in initial cell search is in detail studied. In view of it, the algorithm based on the Fast Fourier Transform (FFT) techniques with quadratic interpolation in the frequency domain is mainly presented. After that,the simulation is carried on and analyse the simulation curves deeply. It ndicates that this algorithm can not only enhance the frequency resolution, but only estimated frequency has high reliability and excellent stability. And it\'s feasible.
