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.

Optical receiver and signal processing method

大二朗 田中, +8 more
TL;DR: In this article, the authors proposed an optical receiver consisting of an analysis unit which analyzes the spectral waveform of the received signal, a determination unit which determines whether the signal spectral wave form is a Nyquist waveform based on the Nyquist's first criterion, and a control unit which, as a result of the determination of determination unit, stops the spectral shaping on the signal of the digital filter.

Antonio A. D'Amico
- 11 May 2015 - 
TL;DR: It turns out that the estimation accuracy is very close to the theoretical limits, even with short observation intervals and small values of the excess bandwidth, and the proposed estimators largely outperform other schemes already known in literature.
