Abstract
A self-excitation detection method for a wireless-signal relay amplification device, an electronic device, and a storage medium are provided. The wireless-signal relay amplification device includes a receiving side, a baseband side, and a transmitting side. The self-excitation detection method includes: when a wireless signal is received at the receiving side, turning off the transmitting side; determining whether a first input power of a wireless signal detected by the receiving side is the same as a second input power of a wireless signal detected by the baseband side and transmitted to the transmitting side by the receiving side; and determining whether self-excitation occurs according to the wireless signal detected by the baseband side, if the first input power is different from the second input power.
