1. An apparatus comprising:
a memory configured to store a computer program, and
a processor configured to execute the computer program stored in the memory, to cause the apparatus to perform operations, the operations comprising:
generating a transmission frame, wherein the transmission frame comprises a frame header and a data domain, phase shift keying modulation is used for the frame header, and phase shift keying modulation or quadrature amplitude modulation with a same bandwidth as the frame header is used for the data domain; and
sending the transmission frame, wherein the frame header comprises a preamble, first phase shift keying modulation is used for the preamble, and any adjacent symbols of a sequence of the preamble are adjacent points on a constellation diagram corresponding to the first phase shift keying modulation.
