Stop-and-go square-contour blind equalization algorithms: design and implementation

New blind equalization techniques based on improved square contour algorithm

“…The scheme implicitly updates phase during convergence and is less likely to converge to incorrect solutions like its parent schemes. In [12] Abrar et al proposed stop-and-go version of the SCA. The proposed scheme outperforms the existing SCA in convergence speed and residual ISI suppression.…”

Dual‐mode multi‐modulus algorithms for blind equalisation of QAM signals

“…If we can tell whether a particular adjustment is correct or not, we may improve the convergence behaviour by making only the right adjustment but bypassing those wrong ones. Such a concept has been applied to blind equalisation and is termed 'stop-and-go' [8][9][10]. In this paper, we develop a stop-and-go DM-MMA for blind equalisers.…”
