1. A method for signal processing, comprising:
determining, by a signal processing apparatus, a sequence {xn} comprising N elements, wherein xn is an element of {xn}, wherein N=24, n=0, . . . , N−1, and xn satisfies xn=A×bn×jn, wherein A is a non-zero complex number, j=√−1, bn is an element of {bn}, and wherein:
bn satisfies bn=u(1−2×Sn), wherein u is a non-zero complex number, Sn is an element of a sequence {Sn} associated with a sequence {qn}, and wherein the sequence {qn} satisfies qn=S(n+M)mod N, M ∈ {0,1, 2, . . . , N−1}, and the sequence {qn} comprises one or more of the following sequences:
{1,0,0,1,0,0,0,0,0,1,1,1,0,1,1,0,1,0,1,1,1,0,0,0}
{1,0,0,1,0,1,0,1,1,1,1,0,0,1,1,0,1,0,0,0,0,0,0,1}
{1,0,0,0,0,1,1,1,0,1,1,0,1,1,1,0,1,0,1,1,1,1,0,0}
{1,0,0,1,0,0,0,1,1,1,0,1,1,1,1,1,0,1,0,0,1,1,1,0}
{1,0,0,1,0,1,1,1,0,0,1,0,1,1,1,1,1,0,1,1,1,0,0,0}; or
{1,0,0,1,0,0,1,1,1,1,0,0,1,1,0,0,0,0,0,0,1,0,1,0};
generating, by the communications apparatus, a signal based on the sequence {xn}, wherein the signal is a demodulation reference signal; and
sending, by the communications apparatus, the signal to a network device.
