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.

Receiver for spread spectrum communication

Naoya Kimura
TL;DR: In this paper, a channel-matched-filter is used to output a Rake-combining result from a digital spread spectrum signal, followed by a carrier recovery circuit which removes an offset of a carrier wave from the combining result; a correlation circuit detects correlation; symbol timing detection circuit which extracts a symbol from the correlation; a symbol determination circuit regenerates data from the symbol; a framer circuit discriminates a frame configuration; and a symbol timing recovery circuit generates a timing phase for each of symbol timings.

Performance Study of a Near Maximum Likelihood Code-Aided Timing Recovery Technique

Imen Hamdi Nasr, +3 more
- 01 Feb 2016 - 
TL;DR: The proposed CA estimator realizes an important gain over the nondata-aided approach (NDA) and achieves a smaller gap when compared to its relative CA CRB, especially at moderate SNR values where modern systems are constrained to work.

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).
