摘要

A receiving unit, receiving method, and semiconductor device that reduce the size of circuits in a receiving unit. A receiving section (2) receives signals sent from a base station and transmitted through a plurality of paths. A path tracking section (5) detects timing of each of the plurality of paths through which the signals received by the receiving section (2) were transmitted. A demodulating section (6) demodulates the received signals by performing a despreading process according to the timing of the plurality of paths detected by the path tracking section (5). A correlation value calculating section (3) calculates a correlation value between the received signals and a spreading code. A destination selecting section (4) provides output from the correlation value calculating section (3) to the path tracking section (5) in the case of performing a path tracking process by the path tracking section (5) and provides output from the correlation value calculating section (3) to the demodulating section (6) in the case of demodulating the received signals by the demodulating section (6).
