| 摘 要： | 针对在快衰落信道中自适应滤波器跟踪性能差的问题，结合容量控制和半盲技术的自适应滤 波原理，提出一种新的结构风险最小化恒模半盲均衡器（SCM-SBE）. 该方法在充分挖掘通 信信号中学习信息的同时，通过容量控制手段补充滤波器自身的结构信息，以学习信息量的 最大化从根源上提高滤波器的跟踪性能. 仿真结果表明，SCM-SBE可以在训练数据较少的条 件下保持良好的跟踪性能，在无线移动通信中具有一定的应用前景. |

| Abstract: | According to the track performance of adaptive filters with poor performance in rapid fading channel,an adaptive filter principle based on capability control and semi-blind technology is presented.And a semi-blind equalizer based on constant modulus characteristic and structure risk minimum(SCM-SRM) criterion is designed.The information of communication signals learning should sufficiently be dug.On the other hand,the structure information of oneself of filters should also sufficiently be dug(by use of a ca... |
| Keywords: | equalization filter capability control semi-blind constant modulus |
