| 摘 要： | 该文提出了一种具有较强抗突发干扰能力的非单点模糊支持向量机判决反馈均衡器。该方法以支持向量机为框架，采用具有前置滤波特性的非单点模糊高斯核函数，利用梯度下降法调整核函数中的可调参数。通过仿真实验，并与支持向量机判决反馈均衡器和传统判决反馈均衡器进行比较，结果证明该方法具有优良的非线性均衡能力和抗突发干扰能力。

| Abstract: | A non-singleton fuzzy support vector machine-based decision feedback equalizer (NSFSVM DFE) is proposed in this paper for severely nonlinear distorted channels with burst jamming. The method adopted non-singleton fuzzy Gauss kernel function with preceding filtering capability of which the tunable parameter is adjusted by gradient-descent algorithm. Simulation is carried out to compare it with other nonlinear channel equalizers. The result shows the method has much better performance on nonlinear equalization and anti-burst jamming. |
