| 摘 要： | 当直接序列(DS-CDMA)系统中的多址干扰非常强时,自适应的盲多用户检测的性能将会严重下降.为了解决这一问题,一般的做法是增加系统的扩频增益,但是其取得的效果是有限的.本文将一种新的克罗内克(Kronecker)扩频序列应用到盲多用户检测中,该序列通过普通的扩频序列对自身作Kronecker乘积而生成.理论分析和仿真...

| Abstract: | When the multiple-access interference(MAI) in DS-CDMA system is very strong,the performance of adaptive blind multiuser detection in the system will degrade significantly.The normal way of solving this problem is increasing the length of spreading code.However,the improvement is limited.This study proposed a novel blind multiuser detection scheme with Kronecker spreading code,which is generated by the kronecker product of normal spreading code.Theoretical analysis and simulation show that the Kronecker spre... |
