Wiretap channels with causal and non-causal state information: revisited

Te Sun Han, Masahide Sasaki

The coding problem for wiretap channels with causal channel state information (CSI) available at the encoder (Alice) and/or the decoder (Bob) is studied. We are concerned here part…

Variable-Length Resolvability for Mixed Sources and its Application to Variable-Length Source Coding

Hideki Yagi, Te Sun Han

In the problem of variable-length -channel resolvability, the channel output is approximated by encoding a variable-length uniform random number under the constraint that the va…

Variable-Length Resolvability for General Sources and Channels

Hideki Yagi, Te Sun Han

We introduce the problem of variable-length source resolvability, where a given target probability distribution is approximated by encoding a variable-length uniform random number,…

Numerical Study on Secrecy Capacity and Code Length Dependence of the Performances in Optical Wiretap Channels

Hiroyuki Endo, Te Sun Han, Takao Aoki +1

Secrecy issues of free-space optical links realizing information theoretically secure communications as well as high transmission rates are discussed. We numerically study secrecy…

Polymatroids with Network Coding

Te Sun Han

The problem of network coding for multicasting a single source to multiple sinks has first been studied by Ahlswede, Cai, Li and Yeung in 2000, in which they have established the c…
