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.

Transmitter and receiver impairment monitoring using adaptive multi-layer linear and widely linear filter coefficients controlled by stochastic gradient descent.

Manabu Arikawa, +1 more
- 12 Apr 2021 - 
TL;DR: The results indicate that both Tx and Rx impairments could be individually monitored by using the filter coefficients of adaptively controlled multi-layer SL and WL filters precisely and simultaneously, decoupled by chromatic dispersion and frequency offset, even when multiple impairments existed.

Timing recovery in data communication circuits

Carl Damien Murray, +2 more
TL;DR: In this paper, a timing error detector (TED, 5 ) receives its inputs directly from the output of an ADC and from a decision device (decision device) and is acquired in three stages: a nondecision directed (NDD) stage, a stage for acquiring the remote scrambler and predicting symbols, and a decision-directed (DD) stage during which locally predicted symbols are also used for acquisition.
