Original Abstract

This paper deals with simplification and improvement of data timing synchronization algorithms. Timing error synchronizers are usually the most complicated subsystems in the demodulator, and limit the DSP technique used for the high-rate application. This article is focused on feedback timing estimators for PSK modulation schemes, and shows modifications of widely used algorithms, that are suitable for the DSP implementation, as well as reach better parameters of the detection process. The methods applied in the evaluation of a timing error detector, which is a crucial part of the synchronizer, are described in the last part.

Key words in English

Additive white Gaussian noise, delay lock loop, digital signal processing, early-late detector, ML criterion, Mueller-Mueller detector, normalized timing error variance, phase shift keying, timing synchronization, timing error detector, raised-cosine pulse shaping, zero-crossing detector
