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.

Abstract: A method for encoding a channel using a parallel convolutional encoder is disclosed. The method includes the steps of a first step for performing an encoding operation using a parallel convolutional encoder at the time when a data is inputted into a frame input data register for implementing a channel encoding operation and generating a code symbol, and a second step for storing the thusly generated code symbol into an interleaver RAM which is alternately selected by the frame unit.
