A method for extracting information from a first received signal (y 1 ) and from a second received signal (y 2 ), includes a step of buffering said first received signal (y 1 ) until receipt of said second received signal (y 2 ), generating a combined signal (y) from said first received signal (y 1 ) and said second received signal (y 2 ), decoding said combined signal (y) in a first decoder (D1) thereby generating a decoded combined signal (c2), further decoding said decoded combined signal (c2) by a second decoder (D2) for generating a first estimated information signal (m2), and further comprises a step of decoding said first received signal (y 1 ) in a third decoder (D3) thereby generating a decoded first received signal (c 1 ), for further provision to a fourth decoder (D4) for generating a second estimated information signal (m 1 ) and for providing an error indication (e 1 ) of said decoded first received signal , such that in case the error indication (e 1 ) is below a predetermined limit (Emax), said second estimated information signal (m 1 ) is provided , while in case the error indication is equal to or exceeding said predetermined limit (Emax) said first estimated information signal (m 2 ) is provided as an output signal comprising the extracted information from said at least two received signals. Variants of the method, applicable to any number of received signals, as well as various arrangements for performing these methods are disclosed as well.
