PROBLEM TO BE SOLVED: To provide a method for subcarrier mapping for signals in a transmitter of a MIMO-based wireless telecommunication network.SOLUTION: The invention includes mapping between signals in an input signal sequence. Subcarriers are controlled. Thereby, signals transmitted by different antennas at the same time correspond to nonadjacent signals in the input signal sequence. By use of this system, burst errors due to deep channel fading are effectively avoided, and improved diversity gains are provided. |
