摘要翻译：
在过去的十年里，神经网络和核自适应滤波器都被成功地用于非线性信号处理。然而，由于其复杂/不断增长的网络结构，它们的计算代价很高。本文针对复值非线性滤波问题提出了两种随机欧拉滤波器，即线性随机欧拉复值滤波器(LRECF)及其广线性型(WLRECF)，它们具有简单固定的网络结构。研究了非平稳环境下的暂态和稳态性能。导出了解析最小均方误差(MSE)和最佳步长。最后，对复值非线性系统辨识和非线性信道均衡进行了数值仿真，验证了所提方法的有效性。

英文摘要：
  Over the last decade, both the neural network and kernel adaptive filter have successfully been used for nonlinear signal processing. However, they suffer from high computational cost caused by their complex/growing network structures. In this paper, we propose two random Euler filters for complex-valued nonlinear filtering problem, i.e., linear random Euler complex-valued filter (LRECF) and its widely-linear version (WLRECF), which possess a simple and fixed network structure. The transient and steady-state performances are studied in a non-stationary environment. The analytical minimum mean square error (MSE) and optimum step-size are derived. Finally, numerical simulations on complex-valued nonlinear system identification and nonlinear channel equalization are presented to show the effectiveness of the proposed methods.
