Abstract:
The sequences with good correlation properties are widely used in engineering applications, especially in the area of communications. In this paper, the relationships among cross- correlation functions of arbitrary four binary sequences of period N are presented. Based on them, for a sequences set, the relationships between cross-correlation functions and autocorrelation functions are studied, by which we prove that they cannot keep optimal at the same time.
Key words:binary sequence; perfect sequence; cross-correlation function; autocorrelation function
