1. A method for microwave signal correction performed by a receiver, comprising:
- receiving, by the receiver that is a peer device of a transmitter, a first radio frequency (RF) signal from the transmitter;
sampling, by the receiver, the first RF signal to obtain sampling data, and obtaining a feedback IQ signal from the sampling data; and
transmitting, by the receiver, a second RF signal that carries the feedback IQ signal to the transmitter, wherein the feedback IQ signal is used by the transmitter to correct a RF signal transmitted by the transmitter.

Abstract
A method, an apparatus, and a system are provided in various embodiments of the present invention. According to embodiments of the present invention, the receiver samples the frequency signal from the transmitter to obtain sampling data and obtain the feedback IQ signal from the sampling data, and performs signal correction by using the feedback IQ signal. Sampling the received radio frequency signal does not need an additional component. The receiving channel installed in the receiver can be used to receive the radio frequency signal, which reduces the cost and power consumption.
