摘要
基于LCCMA(线性约束恒模算法)提出了一种新的盲自适应多用户检测算法。本文中提出的这种算法适用于多径衰落信道,能很好抵消多址干扰和克服多径衰落。仿真证明,这种算法的性能和基于子空间分解的多用户检测算法的性能相当,但运算复杂度低于子空间算法。因此这种算法的总体性能优于基于子空间分解的多用户检测算法,是值得进一步研究的课题,并使之推广应用。
In this paper, a new LCCMA-based blind adaptive multiuser detection algorithm is proposed. It can be used in multipath channels to suppress multi-address interference and overcome multi-channel fading. Simulations show that this algorithm has equivalent performance but simpler computation as compared with the multiuser detection algorithm based on subspace algorithm. Therefore, the proposed algorithm is of some value in research and application.
