摘要

本研究解决了全双工放大和转发中继（FDR）系统中的同相和正交相位误差（IQE）问题。本文在正交频分复用（OFDM）传输的框架下对该问题进行了分析。我们提出了一个创造性的方法来计算发生在所有终端的IQE，假设调制类型是未知的。此外，不同节点之间的信道脉冲响应被纳入到IQE参数中，避免了像以往研究那样需要解耦。该算法利用与FDR传输相关的重复特性来获得相关参数的最大似然估计。综合仿真验证了所提算法的有效性，证明了相对于主流算法在估计性能上的显著改进。

Assessing IQE for Full Duplex Relaying Schemes With Unidentified Modulation Forms

This study tackles the issue of in-phase and quadrature-phase error (IQE) in full-duplex amplify-and-forward relaying (FDR) systems. This problem is analyzed within the framework of orthogonal frequency division multiplexing (OFDM) transmissions. We propose a creative approach to calculate the IQE occurring at all terminals, assuming that the modulation type is unknown. Moreover, the channel impulse responses among different nodes are incorporated into the IQE parameters, avoiding the necessity for decoupling, as done in prior research. The proposed algorithm draws on the duplication characteristics associated with FDR transmissions to obtain maximum-likelihood estimates of the pertinent parameters. Comprehensive simulations validate the efficacy of the proposed algorithm, demonstrating significant improvements in estimation performance relative to the leading algorithms.
