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.

Closed-form timing function for a high-density magnetic recording channel with partial erasure effect

Tsai-Sheng Kao
- 01 Jul 2011 - 
TL;DR: In this paper, the Muller and Mueller phase detector was derived in the presence of the partial erasure under the assumption that the transition shift has been precompensated, and the derived timing function is a weighted combination of two odd functions.

Analog finite impulse response adaptation method and apparatus

William D. Warner
TL;DR: In this paper, an adaptation block coupled to the AFIR is configured to adjust the pre-cursor coefficient and the post cursor coefficient based on the received signal, the adaptation block further being configured to constrain the values of the precursor and post cursor coefficients to be non-positive.

Synchronization in all-digital qam receivers

Eric R. Pelet
TL;DR: The purpose of this research is to both revise and devise synchronization algorithms / structures for cable digital receivers that are to be implemented in FPGA to recover timing with no knowledge of the transmitted data.

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).
