| 摘要 |
The present invention relates to a method for transmitting a stream of data in a communication system with at least two transmission antennas and a transmitter implementing said method. The method comprises the steps of:
- dividing the stream of data elements in first words of k bits,
- encoding (1) the first words with a non binary code, the first words being the symbols of the non binary code and the size (k) in bits of the code symbols dividing the number of bits per space-time codeword,
- interleaving (2) the encoded symbols by a symbol wise interleaver
- splitting the interleaved bit stream thus obtained into groups of log 2 (M) bits,
- mapping (3) the groups of log 2 (M) bits onto complex symbols using a constellation of M points, then
- coding (4) the complex symbols using a space-time code to obtain space-time code words.
