Abstract: A method involves performing a plurality of acts. The acts include transmitting a first signal stream to a first channel of a multi-channel communications medium while transmitting a second signal stream to a different second channel of the medium. The second signal stream is substantially temporally correlated to the first signal stream. The method includes receiving an SINR measured at a receiver configured to receive signals from the first channel. The SINR is measured while the receiver received the first signal stream. The method includes determining a channel matrix element between the first and second channels or a ratio of said channel matrix element to a diagonal element of the channel matrix. The act of determining is based on the received SINR.

Abstract: The present invention relates to a method for the coded modulation of a sequence of bits u with given a priori probabilities P( u ), comprising the steps of: determining from the a priori probabilities P( u ) of the sequence of bits u a sequence of probabilities P( x ) of individual bits of possible coded versions x of the sequence of bits u , calculating from the sequence of probabilities P( x ) of the possible coded versions x a sequence of symbol probabilities P( s ) of possible sequences of symbols s , said symbols belonging to a given set of symbols, deriving a modulated signal comprising information on the calculated symbol probabilities P( s ).
