The present invention relates to a radio frequency signal receiver, and more particularly, to a radio frequency signal receiver of a communication system, in which local devices exchange a radio frequency signal with each other. The object of the present invention is to provide a radio frequency signal receiver that exactly restores data from a received signal without a complex circuit restoring a phase of a received signal. It is another object of the present invention to provide a radio frequency signal receiver that eliminates noise when the noise is included in the received signal, estimates an exact data rate of the received signal, and exactly restores received information based on the estimated data rate thereof. The radio frequency signal receiver includes: a phase converting unit converting a phase of a received digital signal to predetermined angles to produce a plurality of output signals having different phases; and decoding units decoding the plurality of output signals from the phase converting unit, respectively. According to the present invention, data may be restored from a received signal without a complex circuit restoring a phase of a received signal. Moreover, when noise is included in the received signal, the noise is eliminated, an exact data rate of the received signal is estimated, and received information may be exactly restored.
