چکیده
In this letter, we propose a polarity decision carrier recovery algorithm that is useful for carrier acquisition in high order QAM. The PD (Phase Detector) output and its variance characteristic are mathematically derived and the simulation results are presented. The proposed algorithm shows enhanced acquisition performance especially for large frequency offset. key words: carrier recovery, QAM, phase detector

A novel combined algorithms for 32-QAM carrier recovery
In this paper a novel method to realize the synchronization process in case of 32-QAM will be presented. The system is based on the times-n carrier recovery and doesn’t depend on data decision. Starting from the Park and Ahn method which tracks, after a non linearity, the carrier recovery only for the in-phase symbols of a 16-QAM modulation, the proposed method combines a Phase Lock Loop and a ...
متن کاملKalman Filtering Applied to Carrier Recovery of High- Order Qam Signals
A carrier synchronization algorithm for high-order QAM modulated signals that uses Kalman filtering techniques shows fast acquisition times and good frequency tracking performances. The algorithm relies on a decision directed extended Kalman filter combined with a lock detector which determines the status of the synchronization process, modifying consequently the filter parameters. Simulations ...
متن کامل64-qam Carrier Synchronization by an Extended Kalman Filtering
High Order Quadrature Amplitude Modulation (QAM) is a high-bandwidth-efficient modulation scheme employed in the wireless communications. For this type of modulation, one of the most important problems is carrier recovery to allow a coherent demodulation. To extract correctly the transmitted symbols as the carrier frequency offset between the transmitter and receiver is inevitable, the receiver...
متن کاملAn adaptive algorithm for reducing phase error in digital carrier recovery for high-order QAM signals
This paper describes an adaptive software aided technique for phase error reduction in digital carrier recovery (CR) for high-order Quadrature Amplitude Modulation (QAM). Simulations and analytical results illustrate a phase error variance improvement of at least 30 dB compared to conventional CR, leading to more than 3 dB processing gain enhancement for high-order QAM, using the simple 4th pow...
متن کاملHardware-Efficient Coherent Digital Receiver Concept With Feedforward Carrier Recovery for -QAM Constellations
This paper presents a novel digital feedforward carrier recovery algorithm for arbitrary -ary quadrature amplitude modulation ( -QAM) constellations in an intradyne coherent optical receiver. The approach does not contain any feedback loop and is therefore highly tolerant against laser phase noise. This is crucial, especially for higher order QAM constellations, which inherently have a smaller ...
