Patent ID: 7366249

Claim:
A method for transmitting data in a telecommunication system including at least one transmitter provided with Nt transmitting antennas and at least one receiver provided with at least one receiving antenna, which method includes a bit encoding step for generating encoded data bits, a bit interleaving step for permutating said encoded data bits, and a modulation step for producing symbols representative of the permutated bits, each symbol featuring a plurality of components of M bits each, and being intended to be transmitted over communication channels established between the transmitting and receiving antennas, the method characterized in that the bit interleaving step includes a bit demultiplexing sub-step for extracting from the encoded data bits a plurality of bit sequences, each sequence being intended to be transmitted by one of the transmitting antennas, a sequence interleaving sub-step for permutating the bits of each bit sequence produced by the demultiplexing sub-step, a sequence storing and segmenting sub-step for memorizing all the permutated sequences produced by the sequence interleaving sub-step and dividing said sequences into segments having each a predetermined length, and a segment shifting sub-step for simultaneously applying circular shifts to the segments of different ones of the permutated sequences produced by the sequence storing and segmenting sub-step, so that each shifted segment ends up shifted by at least M bits with respect to all other simultaneously shifted segments.
