METHOD AND DEVICE FOR SPACE-TIME ENCODING

摘要

The invention relates to a method for transmitting a signal representative of a source signal S to be transmitted via a transmission channel in a multi-antenna system including n t transmission antennas and n r reception antennas. According to the invention, the modulation constellation C of said source signal S has a diversity degree n, n being an integer higher than or equal to 2, and such a method comprises the following steps: space-time encoding by means of the application, to said source signal S, of an extended space-time encoding matrix X having a size n t x (n x n r ) for outputting an encoded signal; and transmitting said encoded signal using said n t transmission antennas.
