Carrier Frequency Offset Estimation Based on Circular Harmonic Expansion for Optical Coherent M-QAM Communication Systems

We consider in this paper the problem of phase offset and Carrier Frequency Offset (CFO) estimation for Low-Density Parity- Check (LDPC) coded systems.. We propose new blind

Data-aided schemes are more suitable for applications re- quiring fast and reliable synchronization. A popular algorithm to perform timing synchronization and frequency offset

In particular, initializing the simulated annealing algorithm by QCI and carefully choosing the cooling parameters, normally results in a constellation with slightly higher PAMI,

Abstract- This paper investigates the impact of carrier frequency offset (CFO) and sampling frequency offset (SFO) on the performance of different MIMO-OFDM schemes with

A weighted-sample based CFO compensation that can be efficiently implemented in either time- or frequency-domain is proposed. It has been numerically and experimentally

Joint Estimation of Carrier Frequency Offset and Channel Complex Gains for OFDM Systems in Fast Time-varying Vehicular Environments.. ICC 2010 - IEEE International Conference

The algorithm has been designed to work both with parametric L -path channel model (with known path delays) and equivalent discrete-time channel model to jointly estimate the

We proposed a method for the joint estimation of the channel impulse response and the carrier frequency offsets for an uplink OFDMA system. The CFO estimates are then used to
