| 摘 要： | 提出了一种基于前馈神经网络的盲多用户检测算法，该算法基于最小平均峰度准则构造了一个代价函数，给出了算法的约束条件，利用罚函数方法对带约束的代价函数进行优化，获得前馈神经网络网络权值的迭代公式，从而实现盲多用户检测。计算机仿真结果表明，新算法具有较强的多址干扰抑制性能。

| Abstract: | A novel blind multi-user detection algorithm based on feed-forward neural network(FNN) is proposed in the paper.A cost function based on Least Mean Kurtosis(LMK) criterion is founded,and the restraint condition of cost function is deduced.Weights and parameters of feed-forward neural network are optimized by punishment function,iterative formulas of FNN are obtained,and then blind multi-user detection algorithm is realized.Simulation results indicate that the novel algorithm has lower bit-error ratio and better convergence ability. |
