A New Method for Employing Feedback to Improve Coding Performance
Aaron B. Wagner, Nirmal V. Shende, Yücel Altuğ
We introduce a novel mechanism, called timid/bold coding, by which feedback can be used to improve coding performance. For a certain class of DMCs, called compound-dispersion chann…
On exact asymptotics of the error probability in channel coding: symmetric channels
Yücel Altuğ, Aaron B. Wagner
The exact order of the optimal sub-exponentially decaying factor in the classical bounds on the error probability of fixed-length codes over a Gallager-symmetric discrete memoryles…
Information Theoretic Analysis of the Fundamental Limits of Content Identification
Sait Tunc, Yucel Altug, Serdar Kozat +1
We investigate the content identification problem from an information theoretic perspective and derive its fundamental limits. Here, a rights-holder company desires to keep track o…
Minimax Rényi Redundancy
Semih Yagli, Yücel Altuğ, Sergio Verdú
The redundancy for universal lossless compression of discrete memoryless sources in Campbell's setting is characterized as a minimax Rényi divergence, which is shown to be equal to…
Refinement of the random coding bound
Yucel Altug, Aaron B. Wagner
An improved pre-factor for the random coding bound is proved. Specifically, for channels with critical rate not equal to capacity, if a regularity condition is satisfied (resp. not…
The third-order term in the normal approximation for singular channels
Yucel Altug, Aaron B. Wagner
For a singular and symmetric discrete memoryless channel with positive dispersion, the third-order term in the normal approximation is shown to be upper bounded by a constant. This…
