A Rake receiving system distributes parts of a receiving signal to fingers for producing weighted parts, and supplies the parts of receiving signal to a pass controlling sub-system; the pass controlling sub-system checks the parts to see whether or not the correlative electric power of each part is equivalent to an average noise power, and each finger calculates a ratio of electric power between an expected receiving signal and non-expected receiving signal; when the correlative electric power is equivalent to a noise power, the associated weighted part is deleted from the Rake synthesis; when the ratio is lower than a threshold, the associated weighted part is also deleted from the Rake synthesis.
