一种新的变步长部分秩自适应信道均衡方法
A Novel Adaptive Channel Equalization Method Using Variable Step-Size Partial Rank Algorithm
摘要：
最近已经引入了一个框架，其中大量的经典和现代自适应滤波器算法可以被视为特殊情况。可变步长（VSS）归一化最小均方（VSSNLMS）和VSS仿射投影算法（VSSAPA）是可以由该通用自适应滤波器覆盖的自适应算法的两个特定示例。本文在一般VSS自适应滤波器的基础上，提出了一种新的VSS部分秩（VSSPR）自适应算法，并将其用于信道均衡。与标准的NLMS算法和最近提出的AP算法相比，该算法在抑制噪声和符号间干扰（ISI）方面有很好的性能。
英文摘要：
Recently a framework has been introduced within which a large number of classical and modern adaptive filter algorithms can be viewed as special cases. Variable Step-Size (VSS) normalized least mean square (VSSNLMS) and VSS Affine Projection Algorithms (VSSAPA) are two particular examples of the adaptive algorithms that can be covered by this generic adaptive filter. In this paper, we introduce a new VSS Partial Rank (VSSPR) adaptive algorithm based on the generic VSS adaptive filter and use it for channel equalization. The proposed algorithm performs very well in attenuating noise and inter-symbol interference (ISI) in comparison with the standard NLMS and the recently introduced AP algorithms.
