Abstract
In the apparatus and method for separating carrier of multicarrier wireless communication receiver system, each carrier separation is performed after a quantization in a wireless communication receiver system such as a received multicarrier CDMA (Code Division Multiple Access) etc., to thereby reduce the whole number of quantizers and separate multicarrier from a received signal. For that, the apparatus for separating the carrier of the multicarrier wireless communication receiver system includes an internal oscillating unit for generating internal multicarrier; a plurality of frequency transition units for respectively down-converting the multicarrier generated by the internal oscillating unit and moving it to frequency of '0' as a frequency center; and a plurality of filtering units for individually filtering the respective carrier moved by the plurality of frequency transition units to the frequency center as the frequency of '0', through a low frequency pass band and for providing it as an input of a rake receiver.
