—The combination of the effects of Doppler frequency shifts (due to mobility) and phase noise (due to the imperfections of oscillators operating at a high carrier frequency) poses seri- ous challenges to Orthogonal Frequency Division Multiplexing (OFDM) wireless transmissions in terms of channel estimation and phase noise tracking performance and the associated pilot overhead required for that estimation and tracking. In this paper, we use separate sets of Basis Expansion Model (BEM) coef…

Pilot-Assisted Time-Varying Channel Estimation for OFDM Systems with Phase Noise

In this paper, a novel channel estimation technique is presented to fight against the impairment caused by the rapidly time-varying channel and random phase noise, which is very common in the

Subspace-based phase noise estimation in OFDM receivers

This paper solves the problem of channel and phase noise estimation for an orthogonal frequency division multiplexing (OFDM) radio link by first investigating the subspace in which the phase noise spectral vector lies and then exploiting this information during estimation.

Time variant channel estimation using a modified complex exponential basis expansion model in LTE-OFDM systems

This paper proposes a modification to the well known complex exponential basis expansion model, which is based on the assumed knowledge of the maximum Doppler frequency at the mobile user, to reduce the estimation error up to very high mobile speeds for the OFDMA-based LTE downlink.

Pilot-Based Phase Noise Tracking for Uplink DFT-s-OFDM in 5G

This paper proposes a comparison between several phase noise tracking algorithms for 5G, based on the insertion of dedicated time-domain pilots, and considers two low-complexity algorithms based on a rough but fast processing: an average phase error estimation and a linear interpolation between pilot observations.

Understanding the effects of phase noise in orthogonal frequency division multiplexing (OFDM)

This paper analyzes the performance of OFDM systems under phase noise and its dependence on the number of sub-carriers both in the presence and absence of a phase correction mechanism.

Distribution of the ICI Term in Phase Noise Impaired OFDM Systems

It is shown that the complex Gaussian approximation for the inter-carrier interference term is not valid and that the ICI term exhibits thicker tails, and the validity of the limit distribution, obtained under the assumption of a large number of subcarriers, is shown.

Phase-Noise Compensation for OFDM Systems Exploiting Coherence Bandwidth: Modeling, Algorithms, and Analysis

A new framework for low-complexity PN compensation in orthogonal frequency-division multiplexing systems is proposed and closed-form expressions for normalized mean squared-errors (NMSEs) are derived as a function of critical system parameters, which help in understanding the NMSE behavior in low and high signal-to-noise ratio regimes.

Constrained Phase Noise Estimation in OFDM Using Scattered Pilots Without Decision Feedback

This paper considers an OFDM radio link corrupted by oscillator phase noise in the receiver, namely the problem of estimating and compensating for the impairment, and considers a less complex heuristic scheme that achieves the same objective of restricting the minimizer to the phase noise geometry set.

Pilot Allocation and Computationally Efficient Non-Iterative Estimation of Phase Noise in OFDM

The complexity and performance of the overall PN suppression algorithm together with the proposed pilot allocation approach are evaluated in 5G single-user-multiple-input multiple-output (MIMO) and multi- user- MIMO radio links at 28 GHz carrier frequency, showing clear complexity-performance benefits against a state-of-the-art reference algorithm.
