Abstract
A PSK data transmission method wherein in the presence of disturbances which are harmonics of a common fundamental frequency, the disturbance signals are eliminated by the fact that the symbol duration (T) of the data symbols, to be transmitted, of a baseband signal (B(t)) is selected in such a manner that the period duration of the disturbance signal (S(t)) is an integral multiple N.T of the symbol duration. By forming the difference between symbols separated by N intervals from each other at the receiver side, the disturbance signal (S(t)) is completely suppressed while the data rate can be arbitrarily determined via the choice of N.
