Performance analysis of blind carrier phase estimators for general QAM constellations
Additional Document Info
Large quadrature amplitude modulation (QAM) constellations are currently used in throughput efficient high-speed communication applications such as digital TV. For such large signal constellations, carrier-phase synchronization is a crucial problem because for efficiency reasons, the carrier acquisition must often be performed blindly, without the use of training or pilot sequences. The goal of the present paper is to provide through performance analysis of the blind carrier phase estimators that have been proposed in the literature and to assess their relative merits.
