Abstract:
1. A method, in a sending means in MIMO-based wireless telecommunication network, for mapping signals to subcarriers, comprising: 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; mapping the consecutive signals in a signal sequence to M subcarriers, so that the signals mapped to the same subcarrier are nonadjacent signals in the signal sequence; modulating the signals onto the corresponding subcarriers to which the signals have been mapped, so as to generate multiple modulated signal groups, wherein, every modulated signal group comprises M signals modulated on different subcarriers; and controlling to send said multiple modulated signal groups via different antennas.
