Patent ID: 6993070

Claim:
A method of iteratively detecting and decoding encoded and interleaved symbols transmitted on a transmission channel, said symbols being transmitted on the basis of a sequence of binary symbols, each sequence of received symbols comprising at least specific learning symbols, in addition to the data, hold and tail symbols, wherein said method comprises the steps of: prior to any iteration, running an initial linear estimation of coefficients of the impulse response of the transmission channel Ĥ (z) (l) on the basis of the specific learning symbols transmitted; by iteration: subjecting equalization and decoding process to an iterative process of exchanging a priori information, firstly relating to re-interleaved symbol bits from the decoding process in the case of the equalization process and, secondly, relating to de-interleaved encoded bits from the equalization process in the case of the decoding process; running an updated iterative re-estimation of coefficients of the impulse response of the transmission channel on the basis of the information resulting from the iterative equalization and decoding process; repeating the steps performed by iteration at the next iteration, and wherein said iterative process of exchanging a priori information comprises differentiating between a contribution of the transmission channel and a contribution of the decoding.
