A Carrier Recovery Approach for ATSC Receivers
IEEE Transactions on Broadcasting, 2008This paper presents a method of using the field sync signal to perform carrier recovery for ATSC receivers. This approach ensures a fast, reliable, and accurate receiver carrier frequency and phase recovery even under severely distorted channel conditions.

Iterative carrier phase recovery methods in turbo receivers
IEEE Communications Letters, 2005This letter considers carrier phase recovery in turbo receivers. Firstly, a novel maximum-likelihood (ML) based iterative carrier phase estimator is proposed for coded linear modulations over static phase channels. The proposed carrier phase estimator, combined with the iterative sum-product decoder, performs very close to, the Cramer-Rao bound ...

Towards understanding recovery of hot-carrier induced degradation [PDF]
Microelectronics Reliability, 2018 This article treats the recovery of hot-carrier degraded nMOSFETs by annealing in a nitrogen ambient. The recovery rate is investigated as a function of the annealing temperature, where the recovery for increasing temperatures is in agreement with the ...

Reconfigurable carrier‐recovery loop
Microwave and Optical Technology Letters, 2004AbstractThis 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

Carrier Frequency Recovery Technique in OFDM Systems
Wireless Personal Communications, 2005Orthogonal frequency division multiplexing (OFDM) systems are highly sensitive to carrier frequency errors. In this paper, a new method utilizing pilots to do frequency synchronization in frequency domain is proposed with large estimation range. It needs no such prerequisite assumption that a perfect symbol timing synchronization [IEEE Transactions on ...

Carrier recovery for sub-millimeterwave wireless transmission
2017 IEEE Radio and Wireless Symposium (RWS), 2017The carrier frequencies of wireless systems are expanded to higher and higher frequency bands where huge bandwidths for data-hungry applications can be realized. One of the prospective regions is the sub-millimeterwave band. Wireless transmission needs coherent local oscillators at the transmitter and receiver for efficient operation.

Noise Analysis of a PSK Carrier Recovery DPLL
IEEE Transactions on Communications, 1983In this paper we analyze the synchronization properties of a digital loop conceived for PSK carrier recovery. The effects of a frequency step and additive Gaussian noise are evaluated by means of the Markov chain technique.

A fast and accurate class of carrier recovery schemes
TENCON 2019 - 2019 IEEE Region 10 Conference (TENCON), 2019This paper introduces a class of carrier recovery scheme based on simple trigonometric identities. We revisit carrier recovery schemes that have been in use for many years, and compare their relative performances using quantitative metrics. We show that trigonometric identities can be used to recover carriers faster and better than conventional control
