提出一种全新的基于自适应能量判决门限的小波包变换抑制直接扩通信系统中窄带干扰的方法.-combine WPT and AET to wipe off jam,enact the threshold of every frequency area based on the power of DS signal

this file contain simple example about (dsss) TX and RX channel with bit error rate and processing the received signal with different effect signal to noise ratio...........

Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
