To provide a CDMA receiver and a method thereof capable of performing accurate equalization or interference compensation by selecting a correct dimension for amplitude information and error information being a control signal for equalization or interference compensation.

The CDMA receiver for receiving a spread signal to apply equalization processing and inverse spread processing to the signal includes a control signal adjustment means 32 for adjusting a control signal before the equalization processing to be that suitable for a control signal on the basis of the spread signal. Thus, accurate equalization is performed by selecting a correct dimension for the amplitude information and error information being the control signal for the equalization.
