A method for controlling the transmitter part of a radio transceiver and a corresponding radio transceiver

摘要

The invention relates notably to a method for controlling the transmitter part of a radio transceiver, the transmitter part comprising an IQ modulator, the radio receiver further comprising a receiver part comprising an IQ demodulator, the radio transceiver being dedicated to transmit modulated information signal over an air interface.;According to the invention, the method consists in:storing an IQ modulation vector obtained at IQ modulator and associated to a portion of the information signal;looping the portion of information signal to the receiver part, the information signal having crossed a simulated radio interface between the transmitter part and the receiver part;estimating an error vector by comparing the IQ modulation vector to an IQ demodulation vector obtained by demodulation of the portion of information signal at IQ demodulator; andmodifying transmitter part parameters according to the error vector.
