Abstract :
This paper compared ACF(Auto Correlation Feature) characteristics for ZCD, Kasami and Golay codes. Sequence codes have been used as a spreading sequence in order to overcome ICI(Inter Code Interference) caused by transmitter and MPI(Multiple Path Interference) in receiver. In this paper, we abstracted characteristics of each spreading code and analyzed the properties of them.
