采用SRM准则设计的自适应均衡器

An Adaptive Equalizer Based on Structural Risk Minimum Criterion

针对衰落信道造成的非平稳均衡问题，提出采用结构风险最小化（SRM）准则来扩展设计横向均衡器的思想和方法，理论分析和仿真实验均证实：当学习信息充分时，采用SRM准则的均衡器收敛于Wiener最优解；当学习信息不充分时，采用SRM准则的均衡器与采用最小二乘（LeasteSquares，Ls）准则的自适应均衡器相比性能有一定程度提高。

According to the nonstationary equalization problem because of fading channels, an extended adaptive transversal equalizer based on structural risk minimum （SRM） criterion was presented. Simulation was carried out and the results were that, on condition of study intbrmation sufficiency, a SRM-based equalizer converged to a Wiener optimal solution; and on condition of study information insufficiency, a SRM-based equalizer was better than a least squares based adaptive equalizer
