TRANSMISSION/RECEPTION UNIT WITH BIDIRECTIONAL EQUALIZATION

摘要

The present invention refers to a transmission/reception unit that exchanges data with a remote unit by means of a channel using distributed modulation/demodulation treatment means. The transmission/reception unit include s equalization means (23) to equalize a first signal received from said remote uni t and predistortion means to predistort a second signal transmitted to said remote unit. According to the invention, the unit is characterized in that the modulation/demodulation treatment means operate in a non-linear way and the unit includes means (230) to store information that is representative of a non-linear distortion of said modulation/demodulation treatment means and which defines a non-linear reference, and means (233) to adjust coefficients (CO) in the equaliz ation means (23) according to the signal received from the remote unit and said representative information, the mentioned adjusted coefficients being transmitte d to said predistortion means.
