Abstract: PURPOSE: An apparatus for compensating distortions using multi codes in a code division multiple access(CDMA) system is provided to use parity data received through a redundancy channel to correct errors of user data, so as to efficiently compensate receiving signal distortions caused by a high power amplifier(HPA). CONSTITUTION: An energy calculator(418) calculates each symbol energy decided by multi codes during one symbol section from signals received through many parallel data channels and redundancy channels. A parity examiner and code inverter(502) performs a parity examination with symbol data to decide whether an error is generated. If the error is generated, the parity examiner and code inverter inverses a code of a symbol having a least energy to correct the error. A multiplier(401) multiplies the signals received through the parallel data channels and the redundancy channels by pseudo-noise(PN) codes, and applies PN back diffusions to the signals. First multipliers(402-405) multiply the PN back diffused signals by conjugate signals to compensate channels of the signals. Second multipliers(406-409) multiply the channel-compensated signals by orthogonal codes to demodulate the channels. Determiners(414-417) accumulate the channel-demodulated signals for one symbol section to determine each symbol.

Abstract: In a receiver, a reference frequency oscillator (RFO) generates a reference frequency signal having a reference frequency (Fref). A clock circuit derives a clock signal (CLK) from the reference frequency signal. A frequency converter (FRC) converts an input signal (RF) in frequency with a conversion frequency (Fconv) so as to obtain an intermediate frequency signal (IF). The conversion frequency (Fconv) is P times the reference frequency (Fref) divided by M, P and M being integers, P being adjustable. A frequency- shift circuit (FSC) is included for shifting the reference frequency (Fref) with a frequency shift (DeltaFref) which is substantially equal to K times the reference frequency (Fref) divided by a typical value of P (Ptyp) K being an integer (DeltaFref=K.Fref/Ptyp). Accordingly, by shifting the reference frequency (Fref) with the aforementioned frequency shift (DeltaFref), it can be prevented that the clock signal (CLK) causes interference in a channel to which the receiver needs to be tuned, without substantially affecting tuning accuracy. There will always be a value of P for which the receiver is accurately tuned to the desired channel whether the reference frequency (Fref) is shifted or not.
