Abstract
Radio signals from a base station are received by an antenna, and amplified, filtered, frequency converted and detected in a radio section, to thereby obtain baseband signals. A path search section searches the baseband signals, and detects a peak position in each path. Based on the detected timing relations, a code generator in a DLL section corresponding to each path is operated, to thereby obtain a demodulated output. A buffer section in a timing adjusting section fetches the demodulated output and trues up the phases therein, and the demodulated signals whose phases have been trued up are added in the RAKE synthesis circuit.
