1. send a method for data in a wireless communication system, comprising:

  • Carry out inverse discrete Fourier transform to obtain K time-domain sampling to K the incoming symbol for K sub-band, wherein, each sub-band is associated with the different steering vector in K steering vector;

    AndA part of C the time-domain sampling repeated in a described K time-domain sampling comprises the time-domain sampling list entries of K+C time-domain sampling with acquisition;

    Described time-domain sampling list entries is postponed different sampling period amounts to generate T the time-domain sampling output sequence for T antenna, wherein, each different sampling period measures the different steering vector be associated with in T steering vector, wherein, a described K steering vector is same as the guiding matrix that column vector is formed the guiding matrix that a described T steering vector forms as row vector;

    AndA described T output sequence is sent from a described T antenna.
