Patent ID: 7593477

Claim:
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 bursts transmitted and thereby generating an aggregate linearization transmission spectrum of the N symbols of the linearization training sequence; c) comparing the linearization training sequence transmitted with the linearization training sequence generated so as to train said linearization device, wherein a determined number N1 of symbols of the linearization training sequence sent first belong to a subalphabet of symbols included within said alphabet of symbols, said subalphabet of symbols consisting of symbols which, when considering an aggregate spectrum of the transmission of the N1 symbols, produce a narrower spectrum respective to the aggregate linearization spectrum of the N symbols, and wherein N1 is a determined integer greater than one and the N symbols contain at least one symbol outside the subalphabet of symbols.
