Abstract: PURPOSE: A pre-processing apparatus and method thereof are provided to include price reduction effects by reducing the size of a transmission leakage signal elimination apparatus. CONSTITUTION: A low noise amplification unit(110) amplifies a wireless frequency signal including a transmission leakage signal(103) and a received signal. The low noise amplification unit outputs a reception signal(104) by composing the transmission leakage signal with the received signal. A band pass feedback unit(120) give a feed back to the low noise amplification unit through the band passed transmission leakage signal.
