Title:
DOPPLER FREQUENCY SHIFT-BASED CORRECTION METHOD AND APPARATUS, DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/206258
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides a Doppler frequency shift-based correction method and apparatus, a device, and a computer-readable storage medium. The method comprises: establishing vehicle-to-vehicle (V2V) communication between terminals, the terminals comprising a first terminal and a second terminal; obtaining traveling speeds and directions of the terminals; calculating a Doppler frequency shift between the first terminal and the second terminal; and correcting the communication quality of the V2V communication according to the Doppler frequency shift. By calculating a Doppler frequency shift between two vehicles in a V2V system, and correcting the communication quality of the V2V system, the communication quality is improved, the anti-interference properties of the V2V system are improved, and the accuracy of signal demodulation is increased.
