摘要： The invention relates to an amplitude- and frequency- or phase-modulated radio frequency signal generator (G) that is used for radio emission, comprising: means for generating (GEN) a phase or frequency control signal (D) and an amplitude control signal (F) from a phase or frequency modulation signal (B) and an amplitude modulation signal (C); phase or frequency modulation means (MOD); and a variable-gain radio frequency power amplifier (PA). Said generation means (GEN) comprise means for automatically controlling the amplitude of the output signal (G), and, in addition, adaptive pre-distortion means (40) which are arranged in order to pre-distort the phase or frequency control signal (D) in accordance with the amplitude modulation signal (C) during a permanent operating phase and, during a learning phase, to be adapted from the amplitude modulation signal (C) and from the amplitude control signal (F).

摘要： Disclosed is a linearization training sequence that is transmitted by means of a radio frequency transmitter which is comprised in a mobile terminal or a base station of a radiocommunication system and transmits bursts according to a specific frame structure. Said sequence comprises a specific number N of symbols which are part of a specific alphabet of symbols, N being a specific whole number. At least one specific number N1 of symbols of the sequence that is transmitted first is part of a sub-alphabet of symbols, which is contained in the alphabet of symbols, N1 being a specific whole number that is smaller than or equal to N. The sub-alphabet of symbols consists of individual or a combination of symbols that provide the burst within which the sequence is transmitted with a narrower spectrum than the alphabet of symbols as a whole.
