说明： an investigation on use of chaotic sequence in DS-CDMA. The DS-CDMA systems offer
physical layer security without the need for a significant increase in computation or power requirements. Nowadays, DSCDMA
has been used widely. These systems suffers from multiple access interference because of other users transmitting
in the cell, channel inter symbol interference and additive white Gaussian noise. Codes have an effective role in DSCDMA
system, so M-sequences; gold sequences have been used as spreading codes in DS-CDMA. These sequences by
shift registers and periodic in nature are developed. However, these sequences are not enough and also limit the security.
This paper presents an investigation on use of new type of sequences called chaotic sequences for DS-CDMA system.
These sequences by chaotic maps are generated.
