恒模盲多用户检测算法研究

Study of Constant Modulus Blind Multiuser Detection Algorithm

根据优化理论和L agrange神经网络基本原理,针对线性约束恒模算法(LCCM A),提出了一种恒模盲多用户检测算法,构建了L agrange罚函数,推导出迭代公式.通过仿真实验表明,该算法在误码率、信干比和信道跟踪能力方面均有所改善.

Based on optimization theory and the basic principles of Lagrange neural networks,for linear constrained constant modulus algorithm（LCCMA）,the article proposes a constant modulus algorithm for blind multiuser detection,built Lagrange penalty function,the iterative formula is derived.Through simulation experiments show that the algorithm′s capabilities in the bit error rate,SIR and channel tracking have been improved.
