Метод формирования множества дискретных сигналов с заданными корреляционными свойствами

Abstract

The advantages of noise-like signals in spread spectrum communication systems are noise immunity, secrecy, code division of subscribers, ability to evaluate coordinates of moving ob jects, electromagnetic compatibility, etc. They are based on large ensembles of weakly correlat ed signals. Currently there are no efficient methods for discrete sequences synthesis of optimal minimax criterion. It is also difficult to estimate how close are the known signals to optimal se quences. All known methods for discrete sequences synthesis are based on brute force computa tion, which exceedingly limits their applications. Our paper proposes method that significantly (in comparison with known exhaustion methods) reduces computation complexity of synthesiz ing discrete sequences with certain correlation sidelobe.
