本文讨论了全双工无线电收发机中的相位噪声估计和抑制问题。在全双工无线电收发机中，相位噪声是限制自干扰抑制性能的最关键因素之一。本文提出了一种相位噪声估计和抑制算法。该算法估计质量高，计算复杂度低，不需要有用信号和自干扰信号的同步，因此也适用于远距离通信。该算法的性能进行评估，并与广泛的计算机模拟的最新算法的性能进行比较。
This paper addresses the problem of phase-noise estimation and mitigation in full-duplex radio transceivers. It has been shown before that the phase-noise is one of the most critical factors limiting the self-interference suppression performance in full-duplex radio transceivers. In this paper, an algorithm is proposed for the phase-noise estimation and mitigation. The algorithm has high estimation quality and low computational complexity, and it does not require synchronization of the useful and self-interference signals, so it is applicable also in long-range communications. The performance of the algorithm is then evaluated and compared to the performance of the state-of-theart algorithm with extensive computer simulations.
