Patent ID: 7376203

Claim:
A method for transmitting data in a telecommunication system including at least one transmitter provided with a plural number Nt of transmitting antennas and at least one receiver provided with at least one receiving antenna, said method including: generating encoded data bits, permutating said encoded data bits, and producing symbols representative of the permutated bits, each symbol being represented by a predetermined number of bits intended to be transmitted over communication channels established between the transmitting and receiving antennas, which channels feature a predefined number Ni of channel inputs, permutating step includes, demultiplexing a frame of encoded data bits into a number of bit sequences equal to the predefined number Ni of channel inputs, permutating the bits of each bit sequence produced by the demultiplexing step, and forming groups of Nt interleaved bit sequences successively produced by the sequence permutating step, all sequences of a same group being intended to be transmitted through Nt channels allocated to a same bit rank for all transmitting antennas.
