ABSTRACT:
A system for sending sequences of data to be transmitted includes inputting data sequences to be transmitted and repeating data sequences to be transmitted. Data sequences referred to as "key sequences" which provide a key sequence for each data sequence to be transmitted coming from the input or from the repetition are selected independently of the data and the data sequence to be transmitted. The key sequences are different for data sequences to be transmitted which are separated by at least a predetermined number of other data sequences to be transmitted. Each data sequence to be transmitted is combined with the key sequence corresponding thereto in order to provide a sequence of processed data. Finally, frames successively representing each processed data sequence are sent.
