PROBLEM TO BE SOLVED: To provide a receiver for spread spectrum communication by which a stable reception synchronization acquisition signal is outputted to a reception system without revamping a specific spread spectrum reception correlation device IC, even if any reception detection circuit for detecting phase synchronization lock of a PN code series is connected to the receiver for spread spectrum communication. SOLUTION: A comparator 16, an acquisition and discrimination circuit 17 and a PN series generator 18 are adopted for components of a correlation device IC, and a detection signal level detection circuit 15 is used mainly or an external IC of the correlation device IC 19 to configure the spectrum reception synchronization system. A correlation IC 19 is made independent by adopting the configuration of setting a correlation comparison threshold value not fixed in the correlation IC 19 to be set externally. |
