PROBLEM TO BE SOLVED: To provide a code division multiple access CDMA receiver suitable for RAKE synthesis. SOLUTION: A reception timing detection means 1 detects reception timing for each path with respect to a spread signal denoting the same information via a plurality of efferent paths, and inverse spread means (C1-C3) detect a correlation value between the reception signal and the spread code for each path on the basis of the reception timing. Then storage means (M1-M3) store the correlation values of the same information detected for each path which are mode to correspond to each other, read timing generating means G1-G3 provides a prescribed delay to the reception timing of each path to generate read timing with the correlation value of the same information, path detection means D1-D3, 2 detect a path with fastest reception timing of the same information, a selection means 3 selects the read timing corresponding to the path and a synthesis means 4 synthesize correlation values read from the storage means 3 in the selected read timing. |
