Strong Converse Theorems for Degraded Broadcast Channels with Feedback
Yasutada Oohama
We consider the discrete memoryless degraded broadcast channels with feedback. We prove that the error probability of decoding tends to one exponentially for rates outside the capa…
Strong Converse Exponent for Degraded Broadcast Channels at Rates outside the Capacity Region
Yasutada Oohama
We consider the discrete memoryless degraded broadcast channels. We prove that the error probability of decoding tends to one exponentially for rates outside the capacity region an…
A Fundamental Inequality for Lower-bounding the Error Probability for Classical and Quantum Multiple Access Channels and Its Applications
Takuya Kubo, Hiroshi Nagaoka
In the study of the capacity problem for multiple access channels (MACs), a lower bound on the error probability obtained by Han plays a crucial role in the converse parts of sever…
First- and Second-Order Coding Theorems for Mixed Memoryless Channels with General Mixture
Hideki Yagi, Te Sun Han, Ryo Nomura
This paper investigates the first- and second-order maximum achievable rates of codes with/without cost constraints for mixed {channels} whose channel law is characterized by a gen…
