Abstract

A method for performing a space-time coding of an information signal to be transmitted by a multi-channel communication system includes demultiplexing received signals into at least two first space-time coded signals and at least two second space-time coded signals, obtaining a first decoding output signal by using a first decoder performing a first space-time decoding based on the at least two first space-time coded signals and a first a-priori probability signal, applying the output of one of a first decoder or a first conversion unit converting the output of the first decoder to a first substracting unit where an a-priori information signal is subtracted, scrambling the output of the first subtracting unit so as to generate a scrambled extrinsic information, applying one of the scrambled extrinsic information or an output of a second conversion unit converting the scrambled extrinsic information as a second a-priori probability to a second decoder receiving that at least two second space-time encoded signals, applying the output of one of the second decoder or a third conversion unit converting the output of the second decoder to a second subtracting unit which has another input…
