| 摘 要： | 提出的基于免疫算法的Hopfield神经网络多用户检测器，将扰乱的Hopfield神经网络多用户检测器的输出作为免疫算法的初始种群，利用了免疫算法的全局收敛的特点，从而克服了Hopfield易收敛到局部能量最小点的缺点。理论分析和仿真结果表明：该检测器具有良好的抗多址干扰和抗远近效应的能力。

| Abstract: | The Hopfield neural network multi-user detection based on immune algorithm proposed in this paper takes the disturbed output of the Hopfield neural network multi-user detection as the initial population of the immune algorithm. It takes the feature of the global convergence of the immune algorithm thus hurdled the disadvantage of Hopfield which easily converges the minimum of local energy function. Theoretical analyses and the computer simulation results show that the detection has good performances both in multiple-access interference resistance and near-far effect resistance. |
