Proof of Convergence for Correct-Decoding Exponent Computation
Sergey Tridenski, Anelia Somekh-Baruch, Ram Zamir
For a discrete memoryless channel with finite input and output alphabets, we prove convergence of a parametric family of iterative computations of the optimal correct-decoding expo…
Channel input adaptation via natural type selection
Sergey Tridenski, Ram Zamir
We consider a channel-independent decoder which is for i.i.d. random codes what the maximum mutual-information decoder is for constant composition codes. We show that this decoder…
Channel Input Adaptation via Natural Type Selection
Sergey Tridenski, Ram Zamir
For the model of communication through a discrete memoryless channel using i.i.d. random block codes, where the channel is changing slowly from block to block, we propose a stochas…
Exponential Source/Channel Duality
Sergey Tridenski, Ram Zamir
We propose a source/channel duality in the exponential regime, where success/failure in source coding parallels error/correctness in channel coding, and a distortion constraint bec…
