论文摘要
我们考虑一个基本的通信和传感设置，该设置包括发射器，接收器和传感器。发射器通过离散的无内存通道将编码的序列发送给接收器，并且接收器对解码序列感兴趣。另一方面，传感器通过两个可能的离散无内存通道之一拾取了传输序列的嘈杂版本。传感器知道传输序列，并希望区分两个可能的通道，即确定给定输入产生输出的通道。我们研究了渐近状态中通信与传感之间的权衡，该方案是根据接收器对传感器的歧视误差指数的编码率而捕获的。我们表征了具有输入成本限制的一般离散无内存通道的最佳利率实现权衡。
We consider a basic communication and sensing setup comprising a transmitter, a receiver and a sensor. The transmitter sends an encoded sequence to the receiver through a discrete memoryless channel, and the receiver is interested in decoding the sequence. On the other hand, the sensor picks up a noisy version of the transmitted sequence through one of two possible discrete memoryless channels. The sensor knows the transmitted sequence and wishes to discriminate between the two possible channels, i.e. to identify the channel that has generated the output given the input. We study the trade-off between communication and sensing in the asymptotic regime, captured in terms of the coding rate to the receiver against the discrimination error exponent at the sensor. We characterize the optimal rate-exponent trade-off for general discrete memoryless channels with an input cost constraint.
