Original Abstract

Improvements of data timing synchronization algorithms applying an augmentation of zero cross error detector are presented in this paper. Describing methods are destined for high speed PSK coherent demodulator. Timing error synchronizers are usually the most complicated subsystems in the demodulator, and they can be often limitary for their implementation in the DSP hardware above all for high-rate data transmission. This contribution is focused on feedback timing estimators based on ML-criterion. There are analyzed a modification of zero crossing detection and shown an easy implementation into DSP system.
