摘要： An interleaver (ER) is dedicated to interleaving of interleaving units representing a selected number of services grouped into periodic frames within a long period time interleaving radio communication network. The said interleaver (ER) comprises processing means (MT1) responsible for decomposing each frame into a chosen number of group(s) of service of constant respective durations, and then for distributing the interleaving units of each group into so-called spreading time intervals of constant respective durations spaced apart within a time interleaving period according to a period equal to the period of the frames.
