FORMATION APPARATUS AND METHOD OF A SEQUENCE FAMILY CAPABLE OF PROVIDING THE PROGRESSION GROUP WHICH IS STRONG ON SECURITY FOR THE CHANNEL SPREADING OF A COMMUNICATIONS SYSTEM

摘要

PURPOSE: A formation apparatus and method of a sequence family are provided to overcome data saturation limit by rapidly increasing the number of sequence data which can be included in one channel.;CONSTITUTION: A communications system creates a sequence having a cycle by using logarithmic function of a finite field(110). The communications system compartmentalizes the sequence based on the cycle and arranges the sequence to matrices(120). The communications system selects and stores representative rows which are cyclically inequivalent/distinct from arranged matrices(130). The communications system creates a sequence family(140). The asymptotic size of the progression group is equal to involution.;COPYRIGHT KIPO 2012
