摘要

在本文中，我们提出了一种新的基于导频的信道和载波频偏(CFO)估计方案。我们开发了两个独立的信道场景的估计器，互反和非互反。我们使用仿真来绘制所提出方案的均方误差(MSE)性能，并表明它在两种情况下都收敛于相应的Cramer-Rao界(CRB)。

On the Performance of Two-way Relays in the Presence of Frequency Offsets

In this paper, we present a novel pilot-based Maximum Likelihood (ML) estimation scheme for the channel and carrier frequency offset (CFO) in amplify-and-forward (AF) two-way relay networks (TWRNs). We develop an estimator for two separate channel scenarios, reciprocal and non-reciprocal. We use simulations to plot the mean-squared error (MSE) performance of the proposed scheme and show that it converges to the corresponding Cramer-Rao bound (CRB) in both cases.
