PROCEDURE FOR THE TRANSMISSION OF DIGITAL DATA THROUGH RADIO CHANNELS AFFECTED BY INTERFERENCE AND DEVICE FOR THE RECEPTION OF DIGITAL DATA TRANSMITTED THROUGH RADIO CHANNELS AFFECTED BY INTERFERENCE.
PROCEDURE FOR THE TRANSMISSION OF DIGITAL DATA THROUGH RADIO CHANNELS AFFECTED BY INTERFERENCE AND DEVICE FOR THE RECEPTION OF DIGITAL DATA TRANSMITTED THROUGH RADIO CHANNELS AFFECTED BY INTERFERENCE.
A PROCEDURE IS PROPOSED TO TRANSMIT DIGITALALLY CODED DATA FROM A RADIO PROGRAM (A), IN WHICH DIGITALLY CODED DATA IS MODULATED IN ACCORDANCE WITH A MODULATION PROCESS, IN PARTICULATE THE OFDM MODULATION PROCESS. THE DATA ARE MODULATED AT LEAST ON A CARRIER WAVE AND ARE TRANSMITTED IN A TRANSMISSION FRAMEWORK. THE PROCEDURE IS CHARACTERIZED BECAUSE THE DATA OF A RADIO PROGRAM (A) IS TRANSMITED AT LEAST ONCE A REPEATED FORM AND, BELOW, THEY ARE ASSESSED JOINTLY; COMPLEX VALUES (20, 21) PREPARED BY THE DEMODULATOR CIRCUIT (53) ARE ADDED. THE INVENTION TREATS ALSO OF A DEVICE FOR RECEIVING DIGITALALLY CODIFIED DATA FROM A RADIO PROGRAM (A), IN WHICH IS PROVIDED, IN ADDITION TO A HIGH FREQUENCY CONVERSION PHASE (51), AN ANALOG / DIGITAL TRANSFORMER (52) AND A DEMODULATOR CIRCUIT (53), AN INTERMEDIATE MEMORY (57), IN WHICH THE TIME INTERVAL DATA OF THE RADIO PROGRAM (A) DURING THE FIRST TRANSMISSION IS STORED TEMPORARILY. FINALLY, IN THE DEVICE THERE IS ALSO A SCHEDULED SUMMARY PHASE (58), IN WHICH THE DATA IS ADDED IN THE INTERMEDIATE MEMORY (57) WITH THE CORRESPONDING DATA WHEN THE TRANSMISSION OF THE RADIO PROGRAM (A) IS REPEATED.
