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.

Estimating clock phase error based on channel conditions

Abdo Ahmad, +5 more
TL;DR: In this article, a clock-data recovery for a modulated signal from a communication channel comprises: receiving the modulated signals and providing one or more analog signals, providing a clock signal based on clock recovery from the digital input streams; and determining a clock phase error estimate associated with the determined clock signal, based at least in part on a sum that includes different weights multiplied by different respective summands corresponding to different sets of frequency elements.
