DIRECT SAMPLING TYPE WIRELESS RECIEVER AND METHOD USING THE SAME THEREOF

摘要

A direct sampling method wireless radio unit and a method thereof for reducing power consumption by employing a multiple input multiple output part are provided to reduce power consumption and sampling speed by sampling RF signal by using reference signal in proportion to the frequency bandwidth of the received radio frequency signal. A standard signal creation unit provides a second reference signal having frequency higher than a first standard signal. A sampling unit(110) samples the radio frequency signal according to the first standard signal. An analog-digital converter(130) converts the sampled signal, sampling from the sampling unit according to the second reference signal, into digital signal. A multiple inputting unit(140) outputs a plurality of phase having the different phase.
