Abstract

This paper presents the performance analysis of new algorithm, called double-ellipse algorithm (DEA), for blind equalization and carrier phase recovery of QAM and cross-QAM signal constellations. The zero-error contour of this algorithm is in the shape of two superimposed ellipses along vertical and horizontal axes. This algorithm combines the benefits of two well-known blind equalization algorithms, the constant modulus algorithm (CMA) and the reduced constellation algorithm (RCA)
