Embodiment Construction
[0030] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0031] In one example, see figure 1 As shown, a multi-carrier expansion processing method, the method includes the following steps:
[0032] S110 The first signal processing unit performs IQ modulation on the data to be sent to obtain each group of single-carrier single-slot IQ data, respectively calculates the shift factor corresponding to each group of the single-carrier single-slot IQ data, and according to the shift factor Each I data and Q data in the corresponding single-carrier single-slot IQ data are shifted and truncated to obtain scaled IQ data corresponding to each group of single-carrier single-slot IQ data, and the carrier sequence number is inserted into After each group of the scaled IQ data is obtained, multi-carrier and same-slot scaled IQ data is obtained, and the first signal processing unit sen...
