This study generalizes Shannon's information theory using nonadditive information content, aligning with nonextensive entropy principles. It explores properties of this new entropy and its connection to codeword length.

Area of Science:

  • Information Theory
  • Statistical Mechanics
  • Theoretical Computer Science

Background:

  • Shannon's information theory provides a foundational framework for data compression and communication.
  • Nonextensive entropy offers an alternative framework for systems with long-range interactions or memory.
  • Generalizing information theory is crucial for understanding complex systems beyond classical assumptions.

Purpose of the Study:

  • To generalize Shannon's information theory through a nonadditive approach.
  • To establish consistency between nonadditive information content and nonextensive entropy.
  • To investigate the properties of nonadditive information entropy and its relationship with coding parameters.

Main Methods:

  • Generalization of the source coding theorem within a nonadditive framework.

  • Adoption of a nonadditive information content measure consistent with nonextensive entropy.
  • Mathematical analysis of the properties of the proposed nonadditive information entropy.

    • Main Results:

    • A generalized information theory based on nonadditive principles has been developed.
    • The nonadditive information content is shown to be consistent with the form invariance of nonextensive entropy.
    • Key properties of the nonadditive information entropy are systematically studied.
    • A relationship between the nonadditivity parameter (q) and codeword length is identified.

    Conclusions:

    • The generalization provides a new perspective on information theory applicable to nonextensive systems.
    • The findings bridge concepts from information theory and statistical mechanics.
    • The identified relationship between nonadditivity and codeword length offers insights for advanced coding schemes.
