PROCEDE DE TRANSMISSION DE MOTS DE CODE CORRECTEUR D'ERREUR NON BINAIRE AVEC MODULATION CCSK, SIGNAL ET DISPOSITIF CORRESPONDANT |
摘要 |
The invention concerns a method for transmitting symbols of non binary error correcting code words via a transmission channel. The method comprises a first modulation associating each code word symbol of p bits with a sequence of at least 2p chips from 2p possible sequences, a second modulation to modulate the phase or amplitude of a carrier signal with the sequences associated with the code words, and a step of transmitting the modulated carrier signal via said transmission channel. According to the invention, the first modulation is a spread spectrum modulation of the cyclic code shift keying type using a basic pseudo-random sequence of at least 2p chips, the possible 2p sequences being obtained by a circular shift of the basic pseudo-random sequence and a cyclic prefix is inserted into each symbol to be transmitted. |
