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

  • receiving a frame including a first modulated sequence, a second modulated sequence, a third modulated sequence and a fourth modulated sequence;

    determining whether the first modulated sequence is modulated by a first modulation scheme;

    determining whether the second modulated sequence is modulated by a second modulation scheme;

    determining whether the third modulated sequence is modulated by a third modulation scheme; and

    determining whether the fourth modulated sequence is modulated by a fourth modulation scheme,wherein the first and fourth modulation schemes are Binary Phase Shift Keying (BPSK), the third modulation scheme is a Quadrature Binary Phase Shift Keying (Q-BPSK), the first modulated sequence immediately precedes the second modulated sequence, the second modulated sequence immediately precedes the third modulated sequence and the third modulated sequence precedes the fourth modulated sequence.
