The antenna receives a first wireless signal. The bandpass filter has a resonance frequency, for retrieving the specific wireless signal from the first wireless signal. The specific wireless signal cannot be retrieved if the resonance frequency deviates. The offset device is coupled to the bandpass filter, for offsetting a deviation of the resonance frequency. The control device drives the offset device when the specific wireless signal is not detected by the bandpass filter. A transmission system utilizing the wireless receiver is also disclosed.
