ABSTRACT:
A system for transmitting n-level data signals by means of an angle-modulated carrier having a constant amplitude and a continuous phase. The constant amplitude enables amplification in non-linear transmitter output stages. Associated with the n-levels are k(k>n) phase variations in accordance with such a rule, depending on preceding phase variations, that the spectrum of the angle-modulated signal becomes narrower. In a symbol interval the phase of the carrier changes by an amount from the sequence extending from -(k-1).pi.
to (k+1).pi.
in increments of 2.pi.
. The receiver is formed by a differential n-phase receiver. The system is used inter alia for radio transmission of digital information.
