Abstract:
A CDMA searcher receiver, comprising:a first correlator having a first input for receiving an input signal having a phase, a second input for receiving a first spreading sequence, and an output that provides a first correlation of the input signal with the first spreading sequence;a second correlator having a first input for receiving the input signal, a second input for receiving a second spreading sequence and an output that provides a second correlation of the input signal with the second spreading sequence;a circuit block having an input coupled to the output of the first correlator, and an output for providing a complex conjugate of the first correlation; anda multiplier having a first input coupled to the output of the circuit block, a second input coupled to the output of the second correlator, and an output for providing a multiplier output signal that is independent of the phase of the input signal.
