ABSTRACT:
In a reception apparatus, a matched filter that has conventionally been arranged in a searcher unit is mounted on an acquisition unit together with a large scale memory. The large scale memory once stores reception chip signals, and thereafter outputs them to the matched filter and to the delay profile calculation unit. A setting register receives an acquisition signal and outputs it to the matched filter. The matched filter performs acquisition of the reception chip signals outputted from the large scale memory, and outputs a despread timing signal to a despread circuit, a code generation circuit and the delay profile calculation unit.
