Abstract
A radio communication apparatus having a rake receiver for searching and combining reception paths. The apparatus includes at least one combination searcher/finger unit which performs a searcher operation for detecting signals on the reception paths and estimates the signal strength of each of the signals. The searcher/finger unit also performs a finger operation which outputs a demodulated symbol in response to a command signal generated by an assignment unit. The assignment unit assigns either a searcher operation or a finger operation to the searcher/finger unit in accordance with the number of reception paths transmitting a signal suitable for demodulation.
