ABSTRACT:
A spread spectrum radiocommunication device includes a plurality of digital data demodulators which are independently operated to track the paths of a multipath radio signal transmitted from a to-be-communicated device and PN code generators each of which has a ROM storing PN codes and which are respectively provided in the digital data demodulators. In a control section, a ROM address latched by an address latch circuit is monitored and a PN address relative value is generated, and the PN address relative value is added to a basic address generated from an address counter in an address adder and the added address is supplied to the PN code ROM to generate a PN code.
