A method for the transmission of digital data by means of phase modulation (PSK) and "frequency hopping", in which symbols are transmitted several times in different transmission sections as synchronization information for coherent demodulation, and wherein weighting factors taking into consideration the existence and influence of a disturbance source are calculated for each symbol. The symbol values are multiplied by these weighting factors before the values of corresponding symbols are linearly combined and utilized for evaluation. |
