Abstract
A signal transmission method includes a radar detection apparatus selecting a transmit frequency band from a predefined or pre-specified first frequency band. The first frequency band is pre-divided into M sub-frequency bands, and the transmit frequency band includes N sub-frequency bands in the M sub-frequency bands, where a bandwidth of the transmit frequency band is greater than or equal to an operating bandwidth of the radar detection apparatus. A sum of bandwidths of any N−1 sub-frequency bands in the N sub-frequency bands is less than the operating bandwidth of the radar detection apparatus. In addition, a minimum quantity of sub-frequency bands is used to transmit a signal.
Claims21
A method, comprising:
- obtaining a preset transmit frequency band comprising a first transmit frequency bandwidth, wherein the preset transmit frequency band comprises N sub-frequency bands, and wherein a first sum of bandwidths of the N sub-frequency bands is equal to the first transmit frequency bandwidth;
- selecting, based on the preset transmit frequency band, an operating bandwidth of a first detection apparatus, wherein the operating bandwidth is occupied by a waveform of a signal transmitted by the first detection apparatus, wherein the operating bandwidth is greater than a second sum of bandwidths of N−1 of the N sub-frequency bands and is less than the first sum of bandwidths of the N sub-frequency bands, and wherein the operating bandwidth comprises a total bandwidth of the N−1 of the N sub-frequency bands and a portion of a bandwidth of one of the N sub-frequency bands;
- and
- transmitting, on the operating bandwidth, a first signal.
An apparatus, comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the apparatus to:
- obtain a preset transmit frequency band comprising a first transmit frequency bandwidth, wherein the preset transmit frequency band comprises N sub-frequency bands, and wherein a first sum of bandwidths of the N sub-frequency bands is equal to the first transmit frequency bandwidth;
- select, based on the preset transmit frequency band, an operating bandwidth of the apparatus, wherein the operating bandwidth is occupied by a waveform of a signal transmitted by the apparatus, wherein the operating bandwidth is greater than a second sum of bandwidths of N−1 of the N sub-frequency bands and is less than the first sum of bandwidths of the N sub-frequency bands, and wherein the operating bandwidth comprises a total bandwidth of the N−1 of the N sub-frequency bands and a portion of a bandwidth of one of the N sub-frequency bands;
- and
- transmit, on the operating bandwidth, a first signal.
A non-transitory computer-readable storage medium comprising instructions that, when executed by one or more processors, cause an apparatus to:
- obtain a preset transmit frequency band comprising a first transmit frequency bandwidth, wherein the preset transmit frequency band comprises N sub-frequency bands, and wherein a first sum of bandwidths of the N sub-frequency bands is equal to the first transmit frequency bandwidth;
- select, based on the preset transmit frequency band, an operating bandwidth of the apparatus, wherein the operating bandwidth is occupied by a waveform of a signal transmitted by the apparatus, wherein the operating bandwidth is greater than a second sum of bandwidths of N−1 of the N sub-frequency bands and is less than the first sum of bandwidths of the N sub-frequency bands, and wherein the operating bandwidth comprises a total bandwidth of the N−1 of the N sub-frequency bands and a portion of a bandwidth of one of the N sub-frequency bands;
- and
- transmit, on the operating bandwidth, a first signal.
