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.

System for transmitting data by a frequency hopping method, in which the data are transmitted in abruptly changing transmission frequency segments (hops), wherein the data in consecutive frequency segments are encoded according to a woven code that comprises the concatenation of an outer and an inner convolutional code, characterized in that encoding is performed according to the woven code with outer warp, wherein user information items are transmitted in one of the frequency segments, test information items of the outer code are transmitted in another of the frequency segments and the test information items of the inner code, together with the user information items and the test information items of the outer code, are transmitted in all the frequency segments.
System for transmitting data by a frequency hopping method, in which the data are transmitted in abruptly changing transmission frequency segments (hops), wherein the data in consecutive frequency segments are encoded according to a woven code that comprises the concatenation of an outer and an inner convolutional code, characterized in that encoding is performed according to the woven code with inner warp, wherein user information items and test information items of the outer code are transmitted together in one of the frequency segments and the test information items of the inner code are transmitted in each case in other frequency segments.
System for transmitting data by a frequency hopping method, in which the data are transmitted in abruptly changing transmission frequency segments (hops), wherein the data in consecutive frequency segments are encoded according to a woven code that comprises the concatenation of an outer and an inner convolutional code, characterized in that encoding is performed according to the woven code with double warp and user information items, test information items of the outer code and the test information items of the inner code are each transmitted in different frequency segments.
System for transmitting data by a frequency hopping method, in which the data are transmitted in abruptly changing transmission frequency segments (hops), wherein the data in consecutive frequency segments are encoded according to a woven code that comprises the concatenation of an outer and an inner convolutional code, characterized in that encoding is performed according to a woven turbo code, wherein about the same code rate is used in each case for the inner and outer convolutional code and user information items and also test information items of the outer and inner codes are each transmitted in separate frequency segments.
