Abstract
There is disclosed 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 given frame structure. The sequence comprises a given number N of symbols which are part of an alphabet of symbols, N being an integer. At least one given 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 an integer 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.
