ABSTRACT:
An apparatus and method for processing data using the complex quadrature phase shift keying (CQPSK) is disclosed. The present invention includes plurality of multiplying units for multiplying a long pseudo noise (PN) code with an in-phase pseudo noise and quadrature pseudo noise, and a results of multiplying with a pilot channel, a dedicated control channel, a voice channel, a high-speed data transmission channel, a result multiplied with channels with gain, filtering units for eliminating noise, subtracting and adding units for calculating final result, and in-phase/quadrature channel outputting unit for outputting I-channel/Q-channel. The present invention can improve data processing speed of a radio channel, increase capacity of data processing in radio communication and also can be applicable to various kinds of radio communication devices transceiving voice, media contents and high-speed data at a same time.
