Abstract:
The present invention aims to provide a method for mapping signals to subcarriers in a sending means of a MIMO-based wireless telecommunication network and an apparatus for the same. It is characterized in that, controlling the mapping of the signals in an input signal sequence to the subcarriers, so that the signals sent by different antennas at the same time correspond to nonadjacent signals in the input signal sequence. With the aid of the present invention, burst error due to deep fading channel can be effectively avoided, and diversity gains can be also improved.
