Abstract
The present invention relates to a system for estimating the error signal required for adjusting the matching equalizer in digital radio links, for modulated signals QAM, in which the following are produced: A) an estimate of the modulus of the transmitted data element and B) an estimate of the error based on the estimate A) and on the signal at the output of the equalizer. The invention also comprises an estimator of the transmitted data, and a circuit which produces the error signal required for the adjustment of the equalizer. In one embodiment, the estimator of the transmitted data is implemented in the form of a power elevator, adders and comparators, while the circuit which produces the signal required for the adjustment of the equalizer is implemented in the form of power elevators, multipliers and adders. <IMAGE>
