摘要:  Binary sequences with good correlation property have many applications, such as wireless communication and cryptography. Gold sequence is a type of pseudo-random sequence and plays a crucial role in telecommunication and satellite navigation. In literature, there are several methods to construct Gold sequences. One of the constructions is via the trace function from extension field of F2. In this talk, we generalize this construction from finite fields of even characteristic to odd characteristics by using multiplicative quadratic character. Thus, we obtain binary sequences which have more flexibility on length while still possessing low correlation property.
