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.

Digital coherent receiver and digital coherent reception method

Yuichirou Sakamoto, +1 more
TL;DR: In this article, a skew detecting unit detects skew between the digital signals, a skew control unit controls the skew of each of the signals, and a demodulating unit demodulates each signal controlled for skew by the skew detection unit.

Method and apparatus for sampled-data partial-response signal timing error detector having zero self-noise

Floyd Martin Gardner, +1 more
TL;DR: In this paper, a signal sampler is used to generate a sampled digital signal representation of a sampled analog signal in response to a sample-time control signal, and a timing error detector is used at an output port.

A novel dispersion and PMD tolerant clock phase detector for coherent transmission systems

Han Sun, +1 more
TL;DR: In this article, a clock phase detector is presented and shown to be tolerant to chromatic dispersion and PMD. The phase detector can be used in a clock recovery circuit for demodulation of 100 Gb/s coherent transmission system.

Timing Recovery in Digital Subscriber Loops

O. Agazzi, +3 more
- 01 Jun 1985 - 
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).
