Optimum Overflow Thresholds in Variable-Length Source Coding Allowing Non-Vanishing Error Probability
Ryo Nomura, Hideki Yagi
The variable-length source coding problem allowing the error probability up to some constant is considered for general sources. In this problem the optimum mean codeword length of…
First- and Second-Order Hypothesis Testing for Mixed Memoryless Sources with General Mixture
Te Sun Han, Ryo Nomura
The first- and second-order optimum achievable exponents in the simple hypothesis testing problem are investigated. The optimum achievable exponent for type II error probability, u…
Variable-Length Coding with Cost Allowing Non-Vanishing Error Probability
Hideki Yagi, Ryo Nomura
We derive a general formula of the minimum achievable rate for fixed-to-variable length coding with a regular cost function by allowing the error probability up to a constant $\var…
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…
Single-Letter Characterization of Epsilon-Capacity for Mixed Memoryless Channels
Hideki Yagi, Ryo Nomura
For the class of mixed channels decomposed into stationary memoryless channels, single-letter characterizations of the -capacity have not been known except for restric…
Overflow Probability of Variable-length Codes with Codeword Cost
Ryo Nomura
Lossless variable-length source coding with codeword cost is considered for general sources. The problem setting, where we impose on unequal costs on code symbols, is called the va…
Second-Order Slepian-Wolf Coding Theorems for Non-Mixed and Mixed Sources
Ryo Nomura, Te Sun Han
The second-order achievable rate region in Slepian-Wolf source coding systems is investigated. The concept of second-order achievable rates, which enables us to make a finer evalua…
Information Spectrum Approach to Overflow Probability of Variable-Length Codes with Conditional Cost Function
Ryo Nomura, Toshiyasu Matsushima
Lossless variable-length source coding with unequal cost function is considered for general sources. In this problem, the codeword cost instead of codeword length is important. The…
Second-Order Resolvability, Intrinsic Randomness, and Fixed-Length Source Coding for Mixed Sources: Information Spectrum Approach
Ryo Nomura, Te Sun Han
The second-order achievable asymptotics in typical random number generation problems such as resolvability, intrinsic randomness, fixed-length source coding are considered. In thes…
