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

On a hybrid preamble/soft-output demapper approach for time synchronization for IEEE 802.15.6 narrowband WBAN
TL;DR: In this paper, a maximum likelihood (ML) based time synchronization algorithm for WBANs is proposed, which takes advantage of soft information retrieved from the soft demapper for the time delay estimation.

Timing Recovery in Digital Subscriber Loops
TL;DR: Emphasis is on those techniques that lend themselves to implementation in MOSLSI technology, where the objective requirement is that timing recovery be implemented on a sampled-data signal (with the minimum possible sampling rate where EC is used).
