Abstract
The present invention provides a spreading code generation circuit and demodulation circuit capable of maintaining reception characteristic of a receiver in a preferable condition, and a grand phase control in a short time, and eliminating necessity of monitoring the phase control amount. According to a plurality of types of control signals output according to change of synchronization timing of the reception base band signal, a spreading code generation circuit performs phase control on sample time or symbol time or slot time basis for generating a spreading code.
