1) direct sequence spread spectrum (DS) signals
直扩(DS)信号
1.
The problem of estimating direct sequence spread spectrum (DS) signals and direct sequence code division multiple access (DS/CDMA) signals direct from the received signals has been of great research interest with the development of the field of wide-band weak signal processing and the field of communication antagonism.
直扩（DS）信号及直扩码分多址（DS/CDMA）信号的估计方法研究是宽带微弱信号检测与估计以及通信对抗领域的一个重要研究课题。
2) direct sequence spread spectrum(DS/SS) signal
直接序列扩频(DS/SS)信号
3) direct sequence spread spectrum(DS-SS) signal
直接序列扩频(DS-SS)信号
4) direct sequence code division multiple access (DS/CDMA) signals

【诗文】：
想到江陵无一事，酒杯书卷缀新文。紫芽嫩茗和枝采，
朱橘香苞数瓣分。暇日上山狂逐鹿，凌晨过寺饱看云。
算缗草诏终须解，不敢将心远羡君。
