论文摘要
这项工作研究了多个线性时间不变系统的远程估计，而不是共享无线变化的通信渠道。我们通过半马多夫过程对频道状态进行建模，该过程既捕获每个通道状态的随机保持周期又捕获状态过渡。该模型足够通用，可以在快速和缓慢的褪色场景中使用。根据系统参数，我们得出了多传感器 - 渠道系统的必要稳定性条件。我们进一步研究了通道状态信息可用性的延迟和渠道状态的保留周期如何影响稳定性。特别是，我们表明，从系统稳定性的角度来看，快速褪色的频道可能比逐渐减弱的通道更可取。
This work studies remote state estimation of multiple linear time-invariant systems over shared wireless time-varying communication channels. We model the channel states by a semi-Markov process which captures both the random holding period of each channel state and the state transitions. The model is sufficiently general to be used in both fast and slow fading scenarios. We derive necessary and sufficient stability conditions of the multi-sensor-multi-channel system in terms of the system parameters. We further investigate how the delay of the channel state information availability and the holding period of channel states affect the stability. In particular, we show that, from a system stability perspective, fast fading channels may be preferable to slow fading ones.
