A CLASS OF BAND-LIMITED CHIP WAVEFORMS FOR DS-CDMA SYSTEMS
《Journal of Electronics(China)》2007年第1期10-15,共6页Song Rongfang Bi Guangguo Xie Daxiong 
Supported by University Natural Science Research Pro-ject of Jiangsu (No.03KJB510088);National Natural Science Foundation of China (No.60572130).
In Direct Sequence Code Division Multiple Access (DS-CDMA) systems,the chip wave-form affects the implementation,system bandwidth,envelope uniformity,eye pattern and Multiple user Access Interference (MAI). In this pa...

ADAPTIVE STEP-SIZE CONSTANT MODULUS ALGORITHM FOR BLIND MULTIUSER DETECTION IN DS-CDMA SYSTEMS
《Journal of Electronics(China)》2004年第1期10-15,共6页SunLiping HuGuangrui 
Supported by the National Natural Science Fundation of China(No.60172018)
Blind Adaptive Step-size Constant Modulus Algorithm (AS-CMA) for multiuser detection in DS-CDMA systems is presented. It combines the CMA and the concept of variable step-size, uses a second LMS algorithm for the step...

ITERATIVE "ONE-SHOT" DECORRELATION IN DS-CDMA SYSTEMS
《Journal of Electronics(China)》2003年第6期414-422,共9页Du Zheng Zhu Jinkang (PCN&SS Lab, University of Science and Technology of China, Hefei 230027) 
In this paper, an iterative 'one-shot' decorrelator for asynchronous code Division Multiple Access(CDMA) systems is proposed. This decorrelator feedbacks the decorrelated symbols of interfering users before decision t...
