INFORMATION PROCESSING METHOD AND DEVICE

摘要

Disclosed are an information processing method and device, the method comprising: acquiring a local signal to be transmitted via a local transmitter, inserting a first pilot frequency and a second pilot frequency into the local signal to be transmitted, and transmitting the local signal to be transmitted, the first pilot frequency being inserted at the first position of the local signal to be transmitted, the second pilot frequency being inserted at the second position of the local signal to be transmitted, with a first preset duration between the first position and the second position; acquiring the locally transmitted signal via a local receiver; acquiring a remotely transmitted signal via the local receiver, the remotely transmitted signal being transmitted after the insertion of a third pilot frequency and a fourth pilot frequency; the third pilot frequency is inserted at the third position of the remotely transmitted signal, and the fourth pilot frequency is inserted at the fourth position of the remotely transmitted signal, with a second preset duration between the third position and the fourth position; the first pilot frequency is orthogonal to the fourth pilot frequency, and the second pilot frequency is orthogonal to the third pilot frequency; and parsing the locally transmitted signal and the remotely transmitted signal via the local receiver.
