The present invention relates to a wireless repeater capable of effectively removing an echo signal of a signal outputted from the wireless repeater that is fed back and re-input, and to a method of removing the echo signal. By Thus removing an echo signal through replicating an echo signal component in a signal inputted into the wireless repeater and removing the replicated echo signal component from the input signal, the present invention can provide high-quality communication service, and effectively suppress the oscillation of the wireless repeater by not only limiting the size of an input signal from which an echo signal component has been removed to the size of a reference signal, but also by varying a reference signal size value according to input signal size. |
