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...http://www.google.fr/patents/US5519736?utm_source=gb-gplus-shareBrevet US5519736 - Synchronous pseudo-noise code sequence generation circuit
