Device and method for realizing automatic frequency correspondence in wireless receiving equipment

The invention relates to a device for realizing automatic frequency correspondence in wireless receiving equipment. The device comprises a frequency sweeping module for scanning predetermined frequency points and acquiring valid frequency points from the predetermined frequency points, a configuration module for setting the valid frequency points into receiving frequency points, and a detection module for detecting whether or not the receiving frequency points keep valid, and triggering the frequency sweeping module to acquire new valid frequency points when the receiving frequency points are invalid. Through adoption of the device, automatic frequency correspondence of the wireless receiving equipment is realized; operation is simplified; the power consumption and cost are lowered; and the circuit utilization ratio is increased.
