摘要

在本研究中,我们考察了高阶正交幅度调制(QAM)方案在双向多中继网络中的性能。该网络采用三相模拟网络编码和机会性中继选择算法,同时处理不完善的信道状态信息(CSI)和非线性功率放大器(NLPA)。具体来说,我们推导出了一般阶矩形 QAM、六边形 QAM 和交叉 QAM 方案的下限表达式。我们评估了 Nakagami-m 衰减信道的性能,该信道的衰减参数为独立且非同分布的整数值。我们的分析重点是可变增益放大-前向中继与最大比组合接收器的结合。为了计算闭式平均符号错误率 (ASER) 表达式,我们采用了一种基于累积分布函数的成熟方法。我们将推导出的表达式与蒙特卡罗模拟得到的结果进行比较,从而验证了推导出的表达式的准确性。此外,我们还研究了衰减参数、中继节点数量、不完善的 CSI 和 NLPA 对网络性能的影响。

Impact of NLPA and imperfect CSI on ASER performance of QAM schemes for two-way 3P-ANC multiple-relay network

In this study, we examine the performance of higher-order quadrature amplitude modulation (QAM) schemes in a two-way multiple-relay network. This network employs three-phase analog network coding and an opportunistic relay selection algorithm while dealing with imperfect channel state information (CSI) and nonlinear power amplifiers (NLPA). Specifically, we derive lower-bound expressions for general-order rectangular QAM, hexagonal QAM, and cross QAM schemes. We assess performance over Nakagami-m fading channels with integer-valued fading parameters that are independently and non-identically distributed. Our analysis focuses on variable-gain amplify-and-forward relaying combined with maximal ratio combining receivers. To calculate closed-form average symbol error rate (ASER) expressions, we utilize a well-established approach based on cumulative distribution functions. We validate the accuracy of our derived expressions by comparing them to results obtained through Monte Carlo simulations. Furthermore, we investigate how fading parameters, the number of relay nodes, imperfect CSI, and NLPA affect the network’s performance.

期刊介绍: Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
