AI总结:

本文研究含两个速率受限辅助节点的ISAC系统,提出基于状态信息压缩时机的编码方案以获得容量-压缩-失真权衡区域内界,该内界在特殊情况下为紧界。

摘要:

本文研究集成感知与通信(ISAC)系统,该系统包含两个速率受限辅助节点,分别观测信道状态序列和反馈序列。根据压缩与使用状态信息的时机,我们提出的编码方案给出了容量-压缩-失真权衡区域的内界。该权衡通过在传输开始时发送部分状态信息以促进通信,并将剩余部分与反馈信号一起压缩来实现。内界在若干特殊情况下成为紧界。

英文摘要:

This paper studies integrated sensing and communication (ISAC) systems with two rate-limited helpers who observe the channel state sequence and the feedback sequence, respectively. Depending on the timing of compressing and using the state information, our proposed coding scheme gives an inner bound of the capacity-compression-distortion tradeoff region. The tradeoff is realized by sending part of the state information at the beginning of the transmission to facilitate the communication and compressing the remaining part together with the feedback signal. The inner bound becomes tight bounds in several special cases.
