Software-defined radio technology is experiencing more and more attention in modern
communication and radar systems. The main practical challenge in deploying such …

This chapter provides an introduction to adaptive signal processing, covering basic
principles through the most important recent developments. After a brief example for, we …

The widely linear recursive least squares (WL-RLS) algorithm is useful for dealing with
noncircular signals. In this paper, we focus on the theoretical prediction and stability of the …

The frequency of a three-phase power system can be estimated by identifying the parameter
of a second-order autoregressive (AR2) linear predictive model for the complex-valued αβ …

Widely linear estimation for complex-valued data allows for a unified treatment of both
second order circular (proper) and non-circular (improper) signals. We propose the complex …

The widely linear quaternion least mean square (WL-QLMS) algorithm is used to capture
complete second order statistics in quaternion valued mean-square estimation (MSE) …

Based on the constant modulus criterion, a new Widely Linear (WL) blind equalizer and a
novel widely linear recursive least square constant modulus algorithm are proposed to …

In this paper, we present a reduced-complexity widely-linear (RC-WL) inverse square-root
recursive least squares (iQR-RLS) algorithm with the adaptive inverse square-root …

In this paper, the modified widely-linear (WL) frequency-domain equalisation based on the
normalised version of orthogonal gradient adaptive (NOGA) algorithm is proposed for …

Cognitive Radio is an emerging technology that allows an efficient spectrum utilization by
enabling the temporary use of the unused time-frequency resources in a licensed spectrum …
