论文摘要
我们考虑一个基本的关节通信和传感设置，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代码字发送给接收器，并且接收器有兴趣解码发射的代码字。同时，传感器通过两个可能的离散无内存的通道之一拾取了传输代码字的嘈杂版本。传感器知道代码字，并希望区分两个可能的通道，即确定已经生成输出输出的通道。我们研究了渐近制度中的沟通和传感之间的权衡，该方案是根据两种类型的歧视误差指数的通道编码率来捕获的。我们表征了具有输入成本限制的一般离散无内存通道的速率和指数之间的最佳权衡。
We consider a basic joint communication and sensing setup comprising a transmitter, a receiver and a sensor. The transmitter sends a codeword to the receiver through a discrete memoryless channel, and the receiver is interested in decoding the transmitted codeword. At the same time, the sensor picks up a noisy version of the transmitted codeword through one of two possible discrete memoryless channels. The sensor knows the codeword 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 channel coding rate against the two types of discrimination error exponents. We characterize the optimal trade-off between the rate and the exponents for general discrete memoryless channels with an input cost constraint.
