摘要: 提出了一种基于模糊控制的变步长盲多用户检测算法,克服了固定步长自适应算法收敛速度慢的缺点,新算法的步长能够动态地跟随误差及误差的变化率的变化而变化,改善了算法的收敛性能。通过计算机仿真,验证了新算法的有效性。

关键词: 盲多用户检测, 模糊控制, 变步长

Abstract: A variable step-size blind multi-user detection algorithm based on fuzzy control is proposed.It overcomes the shortcoming of convergence rate slow in the fixed step algorithm.Step of new algorithm can dynamically be changed by error and erroneous change.And it improves the performance of the algorithm.Through MATLAB simulation,the validity of new algorithm is verified.

Key words: blind multi-user detection, fuzzy control, variable step-size
