METHOD FOR ESTIMATING THE PHASE AND GAIN OF OBSERVATION DATA TRANSMITTED ON A QAM MODULATION TRANSMISSION CHANNEL

摘要

The invention relates to a method for estimating the gain and / or the phase of observation data (yk) transmitted in QAM modulation. (A) is carried out an iterative estimation of the phase and / or gain parameters. from a specific phase law and / or gain, and an adaptive process for estimating the phase and / or gain parameters is initialized and executed (B), this adaptive process comprising at least one estimation function of these parameters depending on the likelihood-likelihood value, expressed in terms of log-likelihood, of each observation data (yk) vis-à-vis the set of constituent bits of the symbols of the QAM modulation. single-carrier or multi-carrier digital transmissions. / P
