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.

A decision-directed symbol timing recovery circuit for ATSC digital TV receivers

Woo-Jin Song, +3 more
TL;DR: With the proposed method, the proposed scheme works independently of the segment synchronization by extracting timing information from the randomized data symbols even in the extremely small roll-off case, resulting in robust timing recovery with reduced timing jitter compared to the conventional correlation method.
