Abstract
A digital transmission method includes detecting a parameter of the transmission conditions, selecting a distribution of elementary coding step redundancies from a plurality of distributions of elementary coding step redundancies for which the global efficiency is equal to a target efficiency, performing a coding procedure including elementary coding steps with corresponding puncturing steps, and an interleaving step between the elementary coding steps, each of the elementary coding steps adding a redundancy by utilizing the distribution of elementary coding step redundancies, to a useful information to generate a coded information with a redundancy for a transmission, and performing a decoding procedure including elementary decoding steps, deinterleaving and depuncturing steps, and puncturing and interleaving steps corresponding to the elementary decoding steps to obtain an estimation of the useful information item.
