Abstract

The fixed part of a single frequency mobile radio system is made up of a plurality of stations that transmit the same useful signal operating on the same nominal frequency. The signal transmitted by each station is modulated in frequency or phase by a pseudo-random or gaussian noise signal from a noise generator GR with a frequency limited to less than the frequency band occupied by the useful signal. The modulating noise signal can be superimposed upon the useful signal in the basic band or else can modulate the carrier applied to the modulator M.
