Sequence-based signal processing method and signal processing apparatus

A method for signal processing, comprising:

• receiving, a signal transmitted on N subcarriers from a terminal device;
• obtaining, a sequence{xn} comprising N elements, xn is an element of {xn};
• and
• processing, the signal according to the sequence {xn}, wherein N=18, n=0, . . . , N−1, and xn satisfies xn=A×bn×jn, where A is a non-zero complex number, j=√{square root over (−1)}, bn is an element of {bn}, and {bn} is a sequence of unmodulated bits.

An apparatus, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to perform operations comprising:
• determining a sequence {xn} comprising N elements, xn is an element of {xn}, wherein N=18, n=0, . . . , N−1, and xn satisfies xn=A×bn×jn, where A is a non-zero complex number, j=√{square root over (−1)}, bn is an element of {bn}, and {bn} is a sequence of unmodulated bits;
• generating a signal based on the sequence {xn};
• and
• causing a transmitter to send the signal to a network device.
