Sequence-state coding for digital transmission
TLDR
A systematic approach to the analysis and construction of channel codes for digital baseband transmission is presented and state-dependent coding of both fixed and variable length is a direct result.Abstract:
A systematic approach to the analysis and construction of channel codes for digital baseband transmission is presented. The structure of the codes is dominated by the set of requirements imposed by channel characteristics and system operation. These requirements may be translated into symbol sequence properties which, in turn, specify a set of permissible sequence states. State-dependent coding of both fixed and variable length is a direct result. Properties of such codes are discussed and two examples are presented.read more
