A BPSK/QPSK Timing-Error Detector for Sampled Receivers
TLDR
A simple algorithm for detection of timing error of a synchronous, band-limited, BPSK or QPSK data stream is proposed and derivation of the s curve reveals a sinusoidal shape.Abstract:
A simple algorithm for detection of timing error of a synchronous, band-limited, BPSK or QPSK data stream is proposed. The algorithm requires only two samples per symbol for its operation. One of the two samples is also used for the symbol decision. Derivation of the s curve reveals a sinusoidal shape.read more

Analysis and comparison of two discrete phase control digital bit synchronizers
D.W. Paranchych,N.C. Beaulieu +1 more
TL;DR: Random walk models are used to analyze the performance of two digital bit synchronizers that use hard limiting of the received signal, and that allow the estimated timing phase to change by a fixed amount in each symbol period.

Burst transmission symbol synchronization in the presence of cycle slip arising from different clock frequencies
TL;DR: In this paper, the Gardner detector is employed to recover a fixed timing offset, and its output is processed such that timing drifts can be estimated and corrected in a two-step algorithm, and then symbol's timing offset is synchronized in an iterative manner.
