phase shift compensation system for turbo decoder

A of a signal receiver system turbo code transmitted by a transmitter system, turbo encoded, modulated and characterized in that it comprises: - a flexible demapper (1) whose output is connected to a turbo decoder (2), and also comprises an adaptive servo loop comprising: - a measuring generator (3) whose input is connected to the output of the turbo decoder to receive the reliability vector (LLRout) of the result and capable of transforming this vector into a reliability measurement (M (I)), equal to the mean of the smallest reliability values ​​of bits of the word, transmitted To- an estimator (4) phase shifting the output of which is connected a To- compensator (5) of phase positioned upstream of the flexible demapper and adapted to correct the incoming signal of the phase value (φ).
