Filed: 1995-05-31
Abstract: PURPOSE: To repetitively generate the pseudo noise codes of an optional length by initializing a pseudo noise generator for every optionally prescribed value set previously regardless of the largest number of pseudo noise codes that can be generated. CONSTITUTION: The initial state loading means 15A and 15B serve as the circuits which supply the initial value that are loaded by the PN code generators 12A and 12B respectively in an initial mode.
