Why Do Block Length and Delay Behave Differently if Feedback Is Present?
Abstract--For output-symmetric discrete memoryless channels (DMCs) at even moderately high rates, fixed-block-length communication systems show no improvements in their error expon...

Communication under Strong Asynchronism
We consider asynchronous communication over point-to-point discrete memoryless channels without feedback. The transmitter starts sending one block codeword at an instant that is u...

Success Exponent of Wiretapper: A Tradeoff between Secrecy and Reliability
Equivocation has been widely used as a measure of security after Shannon[10]. For an infinite system such as the wiretap channel defined in [2], equivocation is unbounded and so e...
