unbiased sampling

This paper presents a new method for joint estimation of carrier frequency offset and sampling time offset based on the recursive least-square(RLS)algorithm for OFDM systems in the tracking mode.

针对OFDM载波频偏与采样时偏的联合估计问题,提出了一种基于递推最小二乘(RLS)算法的新方法。

In this paper, the sensitivity of sampling frequency offset in orthogonal frequency division MB-OFDM-UWB system is analyzed.

本文分析了MB-OFDM-UWB系统中采样频偏对系统性能的影响,进一步推导出存在采样频偏时接收端符号相位旋转的公式,结果表明,MB-OFDM-UWB系统中采样频偏对系统的影响不仅与 MB-OFDM-UWB数据帧的符号个数、子载波数相关,而且与循环前缀长度有关。
