Abstract
A cooperative precoding method and device. The method includes: obtaining a first sensing and communication signal sent by a first node; obtaining a second sensing and communication signal sent by a second node; updating the first sensing and communication signal; updating the second sensing and communication signal; returning to the step of obtaining a first sensing and communication signal when the signal-to-noise ratio of a signal received by a user and the signal-to-noise ratio of a radar echo signal received by the first node do not meet a preset condition. The solutions enhance sensing performance of nodes while at the same time improve the communication performance of a target user.
