A converse for lossy source coding in the finite blocklength regime
Lars Palzer, Roy Timo · Repository for Publications and Research Data (ETH Zurich) · 2016
We present a converse bound for lossy source coding in the finite blocklength regime.The bound is based on d-tilted information, and it combines ideas from two different converse techniques by Kostina and Verd ú.When particularised to the binary and Gaussian memoryless sources, the new bound gives slightly tighter results in certain blocklength regimes.
