论文摘要
考虑了无内存的状态依赖性广播渠道（BC），发射器希望向两个接收器传达两个私人消息，同时通过广义反馈同时估算各个状态。手头的模型是由关节雷达和通信系统激励的，其中雷达和数据应用程序共享相同的频段。用于与I.I.D.物理降解的BC。国家序列，我们表征了能力折叠式区域。对于一般的BC，我们在容量延伸区域提供内部和外部边界，以及当它等于容量区域的乘积和可实现的失真集时，也是足够的条件。有趣的是，所提出的协同设计极大地胜过一种传统方法，该方法将资源分配为传感或交流。
A memoryless state-dependent broadcast channel (BC) is considered, where the transmitter wishes to convey two private messages to two receivers while simultaneously estimating the respective states via generalized feedback. The model at hand is motivated by a joint radar and communication system where radar and data applications share the same frequency band. For physically degraded BCs with i.i.d. state sequences, we characterize the capacity-distortion tradeoff region. For general BCs, we provide inner and outer bounds on the capacitydistortion region, as well as a sufficient condition when it is equal to the product of the capacity region and the set of achievable distortion. Interestingly, the proposed synergetic design significantly outperforms a conventional approach that splits the resource either for sensing or communication.
