METHOD AND SYSTEM FOR DETECTING AND ITERATIVE DECODING OF RECEIVED SYMBOLS, COUPLED WITH REEVALUATION OF TRANSMISSION CHANNEL COEFFICIENTS

摘要

In order to detect and iteratively decode encoded and interleaved symbols, prior to any iteration, a linear estimation (A) of the transmission channel H_(z)¹ is run on the basis of specific transmitted symbols. Then, by iterations, equalization (B) and decoding (C) process are subjected to an exchange of a priori information (D₂) on the symbol bits resulting from the decoding process (C) in the case of the equalization process (B) and on the encoded bits (D₁) resulting from the equalization process (B) in the case of the decoding process (C) and an updated iterative re-estimation (G,E₂) of the transmission channel is run on the basis of the information resulting from the equalization (B) and decoding (C) process.
