论文摘要
在本文中，提出了热噪声通信（THERCOM）的范式，以供以极低功耗的未来有线/无线网络。进行反向散射通信（反向COM）和可重新配置的智能表面（RIS）基于射频的无链发射机，然后将热噪声驱动的发射器更进一步，可以根据信息位简单地索引电阻器或其他噪声源来实现零信号驱动器的传输。该初步论文旨在阐明理论基础，收发器设计和错误性能推导以及两种新兴的Thercom解决方案的优化：Kirchhoff-law-law-Johnson-Noise（KLJN）安全位交换和无线热噪声调节（Thermod）方案（Thermod）。我们的理论和计算机仿真发现表明，噪声方差检测，并通过仔细优化的决策阈值支持样本方差估计，这是从噪声调制信号中提取嵌入式信息的可靠方法，即使噪声样本数量有限。
In this paper, the paradigm of thermal noise communication (TherCom) is put forward for future wired/wireless networks with extremely low power consumption. Taking backscatter communication (BackCom) and reconfigurable intelligent surface (RIS)-based radio frequency chain-free transmitters one step further, a thermal noise-driven transmitter might enable zero-signal-power transmission by simply indexing resistors or other noise sources according to information bits. This preliminary paper aims to shed light on the theoretical foundations, transceiver designs, and error performance derivations as well as optimizations of two emerging TherCom solutions: Kirchhoff-law-Johnson-noise (KLJN) secure bit exchange and wireless thermal noise modulation (TherMod) schemes. Our theoretical and computer simulation findings reveal that noise variance detection, supported by sample variance estimation with carefully optimized decision thresholds, is a reliable way of extracting the embedded information from noise modulated signals, even with limited number of noise samples.
