Abstract
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.

A method of training a device for linearizing a radiofrequency amplifier which is included within a radiofrequency transmitter of a first equipment of a radiocommunication system, which transmitter is adapted for transmitting bursts according to a determined frame structure, each burst comprising symbols belonging to a determined alphabet of symbols, the method comprising the steps consisting in:
- a) generating a linearization training sequence comprising a determined number N of symbols, where N is a determined integer;
- b) transmitting the linearization training sequence by means of the transmitter in at least certain of the bursts transmitted by the latter;
- c) comparing the linearization training sequence transmitted with the linearization training sequence generated so as to train said linearization device,
- wherein, in step b), the linearization training sequence is included in a sequence of symbols that is also further designed to allow the adjusting of at least one parameter of a radiofrequency receiver of a second equipment of the radiocommunication system with which said first item of equipment communicates.
