PROTECTION CODE FOR S-CDMA SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing interference between codes from different transmission sources in a common synchronous CDMA system. SOLUTION: This invention provides the method for reducing the interference between S-CDMA channels (chips) through the selection of a spread unit function of a 1st sequence for a 1st channel and through the selection of a spread unit function of a 2nd sequence for a 2nd channel that is not in duplicate with the 1st sequence but has an interval.
