Paper abstract
This paper deals with the QAM phase estimation problem. After reviewing some classical solutions (Fourth power estimator and Costas loop), we propose several original improvements: self-adaptive first and second order loops. Furthermore, the performance are compared to the performance of the optimal loops.
