摘要

本文介绍了三种基于自编码器的多输入多输出(MIMO)系统可变有源天线空间调制(AE-VASM)框架,旨在提高系统在高度相关的衰落信道中的鲁棒性和功率效率。通过将动态天线选择与自编码器的联合收发优化能力相结合,所提出的框架有效地减轻了由于天线相关引起的信号退化。框架1作为基线模型,调制数据符号并根据信道变化检测天线指标。框架2通过使用基于相移键控(PSK)的签名将天线索引信息整合到传输信号中来提高性能,从而提高了相关信道中的检测精度。框架3通过在自动编码器内联合编码数据符号和天线索引进一步推进了这种方法,从而在不同信道条件下获得更高的误码率(BER)性能和功率效率。仿真结果证实,框架3始终优于基线和其他框架。这证明了它在复杂信道条件下要求鲁棒和高效调制的下一代无线系统中的潜力。

Autoencoders for variable active antenna spatial modulation in MIMO systems
This paper introduces three novel autoencoder-based frameworks for variable active antenna spatial modulation (AE-VASM) in multiple-input multiple-output (MIMO) systems, aimed at enhancing system robustness and power efficiency in highly correlated Rician fading channels. By integrating dynamic antenna selection with the joint transmitter–receiver optimization capabilities of autoencoders (AEs), the proposed frameworks effectively mitigate signal degradation due to antenna correlation. Framework 1 serves as a baseline model that modulates data symbols and detects antenna indices based on channel variations. Framework 2 improves performance by incorporating antenna index information into the transmitted signal using phase-shift keying (PSK)-based signatures, which enhances detection accuracy in correlated channels. Framework 3 further advances this approach by jointly encoding both data symbols and antenna indices within the autoencoder, leading to superior bit error rate (BER) performance and power efficiency across diverse channel conditions. Simulation results confirm that Framework 3 consistently outperforms the baseline and other frameworks. This demonstrates its potential for next-generation wireless systems demanding robust and efficient modulation under complex channel conditions.
