摘要: 該文利用反演公式求得了m 值復(fù)合邏輯函數(shù)的Chrestenson循環(huán)譜的計算公式, 并由此得到了m 值復(fù)合邏輯函數(shù)的自相關(guān)函數(shù)的計算公式, 進而運用這兩個公式, 給出了m 值復(fù)合邏輯函數(shù)具備平衡性、相關(guān)免疫性的條件, 并對m 值復(fù)合邏輯函數(shù)的自相關(guān)函數(shù)及其性質(zhì)進行了分析; 此外該文還得到有限個m 值復(fù)合邏輯函數(shù)的非零線性和函數(shù)的Chrestenson循環(huán)譜的計算公式。Abstract: This paper presents the formula of Chrestenson spectrum of m-value composition logical function by using inversion formula, and gives the formula of auto-correlation function of m-value composition logical function. Furthermore, this paper gives some conditions under which m-value composition logical function is separate balanced or correlation-immune, and analyzes the auto-correlation function of m-value composition logical function and its charateristic. Moreover, this paper gets the Chrestenson spectrum formular of nonzero linear combination of several m-value composition logical functions.
