ABSTRACT:
The invention relates to a system for transmitting data according to the frequency hopping method. The digital data, which is transmitted in suddenly changing transmission frequency hops, is encoded according to a woven code consisting of an interlinked external and internal convolution code. The data to be transmitted by hop is preferably distributed over several parallel hops sent with different frequencies.
