The relation between signal processing in information science and statistical physics has been intensively discussed. In this article we deal with the random code ensemble with hierarchical structure recently investigated by Merhav. It is known that random code ensemble is closely related to a solvable spin-glass model in statistical physics, called random energy model. Here we show the hierarchical random code ensemble can also be directly mapped to another solvable spin-glass model, generalized random energy model with discrete energy. By investigating this model we show that the performance of hierarchical random code ensemble regarding data compression and channel coding is directly and systematically accessible. |
