摘要

研究了FSE-CMA的渐近特性(即采用戈达尔算法的分数间隔均衡器)。在已知信道和均衡器长度有限的条件下允许完全均衡，证明了FSE-CMA代价函数只允许全局最大值、全局最小值和鞍点。然而，全局最小值集包含了无限范围的密集集，这可能导致数值溢出。

Adaptive fractionally spaced blind equalization

The asymptotic behavior of the FSE-CMA (i.e., fractionally spaced equalizer adapted by the Godard algorithm) is studied. Under conditions on the channel and equalizer finite length that are known to allow perfect equalization, the authors show that the FSE-CMA cost-function admits only global maxima, global minima and saddle points. However, the set of global minima contains dense sets of infinite extent which can lead to numerical overflow.<>
