Abstract

In Code Division Multiple Access system (CDMA), a family of binary sequences with low correlation needs to minimize multiple access interference (MAI). Sequences with low correlation play crucial roles in DS-CDMA(Direct sequence code division multiple access) systems and DS-UWB(DS Ultra wide band) systems.

Low correlation systems are used in many applications in digital spread spectrum communication systems. The correlation values can be computed using the relation between the degree of the polynomial and the number of the roots.

In thesis paper, we propose the extended Zeng-sequences with large family size and high linear span and analyze the correlation of the sequence. A new family of binary sequences include -sequences, GMW-sequences, Kasami- sequences, No-sequences and Zeng-sequences.
