Patent ID: 7873100

Claim:
A reception apparatus using a spread spectrum communication scheme, comprising: an input process unit configured to wirelessly process a reception chip signal and output a plurality of reception chip signals wherein each of the plurality of reception chip signals correspond to a distinct spread code; an acquisition unit configured to perform an acquisition of said plurality of reception chip signals and output a timing signal together with said plurality of reception chip signals; a spread spectrum demodulation unit configured to receive said timing signal, perform a demodulation process of said plurality of reception chip signals outputted from said acquisition unit, and output a combination symbol signal; and an output process unit configured to perform a decode process of said combination symbol signal and output audio data, wherein said acquisition unit includes a memory configured to temporarily hold said plurality of reception chip signals, and a matched filter configured to detect in advance a plurality of acquisition points when despreading in said spread spectrum demodulation unit based on an acquisition signal and said plurality of reception chip signals temporarily held in said memory, wherein said memory simultaneously holds said plurality of reception chip signals which are subjected to a same spread code and outputs said plurality of reception chip signals to said matched filter and said spread spectrum demodulation unit, said matched filter outputs said timing signal to said spread spectrum demodulation unit, and said spread spectrum demodulation unit successively reads said plurality of reception chip signals subjected to said same spread code in order of arrival at said reception apparatus.
