Claim 6:
7. The method according to claim 1, wherein when the value of the delta is 0, the generating a reference signal of a first signal comprises:
performing discrete Fourier transform on elements in a sequence {z(t)} to obtain a sequence {f(t)} with t=0, . . . , L×K−1, wherein when t=0, . . . , L×K−1, z(t)=x(t mod K), and wherein x(t) represents the first sequence; and
mapping elements numbered L×K+delta in the sequence {f(t)} to subcarriers each having the subcarrier number of u+L×p+delta, respectively, to generate the reference signal, wherein p=0, . . . , K−1.
