Patent ID: 7804908

Claim:
A method of transmitting a signal from a transmission chain of a wireless transceiver during transmission periods separated by silence periods, the method comprising: performing a transmission phase during the transmission periods comprising providing initial modulation coefficients in a frequency domain, and respectively modulating sub-carriers to be transmitted from the initial modulation coefficients; associating a storage area to each sub-carrier; performing a calibration phase comprising a) providing a reference modulation coefficient in the frequency domain associated with a chosen sub-carrier, and dynamically measuring power of a corresponding reference signal delivered to the transmission chain, during a silence period, b) calculating from a result of the measurement and from the reference modulation coefficient, a gain correction coefficient for that sub-carrier, c) storing the calculated gain correction coefficient in the storage area associated with the sub-carrier, and d) repeating steps a) to c) for other chosen sub-carriers, with step a) respectively being associated to all chosen sub-carriers performed during a silence period; and performing the transmission phase further comprising correcting the initial modulation coefficients with contents of the corresponding storage areas.
