Abstract
The present invention relates to a digital modulation method and a corresponding modulator. The modulator comprises a transcoder () followed by a FIFO register () and a 2-PSK modulator (). The transcoder codes a binary word of fixed size into a code word of variable size using a transcoding table. The transcoding table codes at least one first binary word, leading to a first number of phase transitions at the output of the modulator, into a second word of size greater than that of the first word, leading to, at the output of the modulator, a second number of phase transitions less than the first number of phase transitions.
