Abstract
The station includes a coded speech signal source having a given digital rate, a modulator for producing a radio signal from the coded speech signal provided by the source, and a redundancy encoder having a coding rate of the form K/N, where K and N are integers such that 0<K<N. An operating mode of the station is selected from at least a first operating mode where the modulator directly receives the coded speech signal and converts it into a radio signal occupying a determined fraction of time on a carrier frequency, and a second operating mode where the redundancy encoder receives the coded speech signal, and the modulator receives the output signal from the redundancy encoder and converts it into a radio signal occupying N/K times the determined fraction of time on a carrier frequency.
