AI总结:
本文通过构造一个二元中继信道反例,证明基于典型序列的容量表征不适用于一般中继信道,并指出该反例借助ChatGPT-6 Astra获得。
AI中文摘要:
我们针对近期一项工作中提出的中继信道容量表征给出了一个反例,该表征基于典型序列的性质。该反例使用了一个二元中继信道,其中包含无噪声的源-目的端分量和二元对称中继链路。一种可达方案超过了所提出的容量表征,从而否证了该表征对一般中继信道容量的适用性。我们强调,该反例是在ChatGPT-6 Astra的辅助下获得的,并且证明过程经过人工努力得以简化。
英文摘要:
We present a counterexample to the relay channel capacity characterization proposed in a recent work, which is based on properties of typical sequences. The counterexample uses a binary relay channel with a noiseless source-destination component and binary symmetric relay links. An achievable scheme exceeds the proposed capacity characterization, thereby disproving the characterization of the capacity for general relay channels. We highlight that the counterexample is obtained with the assistance of ChatGPT-6 Astra and the proofs are simplified with human effort.
