A method of coded modulation of digital data is described, the digital data being divided into parallel signal streams, and the useful bits then being channel coded at different code rates according to their error susceptibility. The useful bits channel coded differently in this way are then scrambled separately in time. The different code rates used and the respective number per transmission frame of the useful bits channel coded at different code rates are signaled to the receivers, so that the receiver is able to perform the descrambling and channel decoding. |
