A demodulator of a Code Division Multiple Access Receiver (CDMA) provides single user pilot code aided coherent demodulation of QPSK/CDMA signals using a switch and squarers instead of multipliers. Additionally, a coherent Multicode (MC) CDMA demodulator with a switch for sharing pilot and data correlator results is presented. This change in the demodulators reduces by one-half the number of additions required in the accumulator part for both, the CDMA and the MC-CDMA receiver.
