Reconfigurable carrier‐recovery loop

Microwave and Optical Technology Letters, 2004
AbstractThis paper proposes a carrier‐recovery loop using a reconfigurable phase shaper. It is based on the five‐port technique, which has the advantage of using mixed circuits to calculate complex power ratios. Different modulation standards can be canceled, since the phase detector's transfer function can be dynamically changed. Furthermore, the loop

Golay code based carrier phase recovery

2008 4th International Conference on Emerging Technologies, 2008
In this paper we present a Golay code based carrier phase recovery scheme. Golay code is a pair of complementary codes. Golay codes have been used for channel coding in communications. We have used the side lobe suppression property of Golay Code in recovery of the phase of the carrier. We begin with the discussion of side lobes suppression property of

OpenFlow: Meeting carrier-grade recovery requirements

Computer Communications, 2013
OpenFlow, initially launched as a technology-enabling network and application experimentation in a campus network, has a disruptive potential in designing a flexible network, fostering innovation, reducing complexity and delivering the right economics. This paper focuses on fault tolerance of OpenFlow to deploy it in carrier-grade networks. The carrier-

Carrier Recovery Techniques using Synchronous Oscillators

MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's, 1986
A Synchronous Oscillator (SO) is a synchronization and tracking network which synchronizes, tracks, filters, amplifies and divides (if necessary) in a single process. It has very good noise rejection properties while maintaining wide tracking range. It acquires very fast in burst mode operation.

Reduced-Jitter Carrier Frequency Recovery

COIN-NGNCON 2006 - The Joint International Conference on Optical Internet and Next Generation Network, 2006
Both the steady-state and transient performances of a carrier frequency recovery loop are improved by simply overlapping the observation intervals for successive frequency offset estimations by half. The proposed scheme does not require any additional hardware circuitry.

Universal carrier recovery for APK signals

Proceedings of the IEEE, 1983
A Costas loop with adjustable quantizers is demonstrated to be capable of carrier recovery for a wide range of Amplitude-Phase-Keyed (APK) modulation formats. Expeximental verification was obtained for QPSK, 8-PSK, and 16-QAM.
