ABSTRACT:
The invention relates to a process for the transmission in blocks of digital information words with a correction capability. This process consists of transmitting in blocks digital information words, each information word having a length of n.sub.1 bits, in which with each sequence of n.sub.2 -k (n.sub.2 >k) of consecutive information words are associated k redundancy words of n.sub.1 bits each in which, for each order i (1<i<n.sub.2), the k bits of order i of the redundancy words are redundancy bits in accordance with a Hamming code (n.sub.2 0k, k). For each set of n.sub.2 linked words, each word is transmitted while being protected by an error detecting code. Several sets of linked words can be interlaced. The words of the same order or rank of each set form a group and the groups can be formed by frames.
