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.

image-construction-by-fft-and-wt
傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR

indi
Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. High Peak-to-Average Power Ratio (PAPR), which leads to power inefficiency in the RF portion of the transmitter, is a major drawback of OFDM.
