ABSTRACT:
A synchronous pseudo-noise (PN) code sequence generating circuit generates a plurality of PN code sequences which should be synchronized with each other. A feedback-type PN code generator generates a master PN code sequence. Each of N code converters, which are provided for each of N channels, converts the master PN code sequence to a PN code sequence of the corresponding channel in accordance with a mask pattern unique to the corresponding channel. The mask patterns for each channel are stored in the corresponding mask memory.
