Sequences of codes generation method for code division multiple access communication network, involves applying transformation operator to initial family for generating family of code sequences, where spectrum of sequence is identical

摘要

The method involves initializing a family of orthogonal sequences (V), and determining an orthogonal transformation operator (U) conditioned by energy of each orthogonal sequence searched in a frequency band from a set of fixed frequency bands. The operator is applied to the initial family of the orthogonal sequences for generating a family of code sequences (W), where spectrum of each generated sequence is identical in each fixed frequency band. An independent claim is also included for a communication system including units for generation of sequences of codes for digital communications.
