The identification capacity region of the compound broadcast channel is determined under an average error criterion, where sender has no state information. We give single-letter formulas for discrete channels and multiple-input multiple-output Gaussian input constraint. theorems apply to general memoryless channels. This in contrast transmission setting, only known special cases, notably degrad...

This article introduces two new approaches in the areas of lexical analysis and context-free parsing. We present an extension, MGLL, generalised parsing which allows multiple input strings to be parsed together efficiently, we enhanced approach exploits this capability. The work provides power formal language specification disambiguation, brings techniques into historically well-studied syntax ...
