1. A self-excitation detection method for a wireless-signal relay amplification device, the wireless-signal relay amplification device comprising a receiving side, a baseband side, and a transmitting side, the self-excitation detection method comprising:
turning off the transmitting side when a wireless signal is received at the receiving 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, in response to the first input power being different from the second input power.
