[0045] Example 1

[0046] refer to figure 2 , which shows a flow chart of specific steps of a multi-carrier data processing method provided in Embodiment 1 of the present invention.

[0047]Step 101: Obtain a data format of an interleaved signal, where the interleaved signal includes at least two antenna signals and at least two carrier data, and the sampling frequencies of the at least two carrier data are the same.

[0048] In this embodiment of the present invention, when the preset clock frequency is a multiple of the sampling frequency of the carrier data, at least two carrier data are interleaved to obtain an interleaved signal. For example, there are three single-carrier two-antenna signals c0a0c0a1, c1a0c1a1, and c2a0c2a1 , where c0, c1, and c2 are three carriers respectively, antenna a0 and antenna a1 correspond to one carrier respectively, the sampling frequencies of the three carriers c0, c1 and c2 are the same, and the preset clock frequency is a multiple of the sam

[0070] refer to Figure 7 , which shows a flow chart of specific steps of a multi-carrier data processing method provided in Embodiment 2 of the present invention.

[0071] Step 201: Acquire at least two carrier data, the sampling frequencies of the at least two carrier data are the same, and the sampling frequency is a factor of a preset clock frequency.

[0072] The preset clock frequency is the operating frequency of the apparatus for executing the multi-carrier data processing method provided by the embodiment of the present invention, for example, the clock frequency of an FPGA (Field Programmable Gate Array, field programmable gate array). provided by the present invention Figure 4 The NCO model shown as an example, the preset clock frequency is the operating frequency of the NCO model, and the Figure 4 In the NCO model shown, the operating frequencies of each module are the same, which can be represented by the clock frequency.
