PROBLEM TO BE SOLVED: To provide a CDMA base band reception device which can highly precisely by synchronized with a peripheral base station in a short time at the time of searching a peripheral cell. SOLUTION: In the CDMA base band reception device, a maximum correlation peak phase detector 3 detects plural long code phase candidates only from a short code and known base station delay profile generators 5-1 to 5-m generate delay profiles for plural base stations during reception, a known base station phase detector 10 deletes the long code phase of the known base station from the long code phase candidates, a long code generator 11 generates a long code from the long code phase candidate from which the known base station is deleted, a threshold judgment unit 13 detects the long code which takes the maximum correlation value and which is peculiar to the base station from correlation values correlated with a spread modulation signal by a spreading code generated from the generated long code and short code and synchronization is executed. |
