a method whereby a linearization training sequence is designed to be transmitted by means of a radiofrequency transmitter incorporated in a mobile terminal or a base station of a radiocommunication system comprising a fixed network. The sequence is adapted for transmitting bursts in accordance with a specific frame structure. Besides, the sequence is included in a sequence of symbols further designed to enable the transmission chain parameters to be adjusted.

Method and device for training an RF amplifier linearization device, and mobile terminal incorporating same

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.
