If a system and its observation are both represented in state space with linear equations, the
system noise and the measurement noise are white, Gaussian, and mutually uncorrelated …

We address a p-shift finite impulse response (FIR) unbiased estimator (UE) for linear
discrete time-varying filtering (p= 0), p-step prediction (p>; 0), and p-lag smoothing (p<; 0) in …

The problem of automatic modulation identification (AMI) is one of the main challenges that
faces orthogonal frequency division multiplexing (OFDM) software-defined radio (SDR) …

Measurements are often provided in the presence of noise and uncertainties that require
optimal filters to estimate processes with highest accuracy. The ultimate iterative unbiased …

In this paper, the emerging orthogonal time frequency space (OTFS) modulation is firstly
restructured as a precoded orthogonal frequency division multiplexing (OFDM) system, so …

In this paper, we develop frequency-domain phase noise estimation schemes for an
orthogonal frequency division multiplexing (OFDM) system that utilize the geometrical …

This paper proposes an iterative OFDM millimeterwave receiver employing low-complexity
decision-directed phase noise compensation (DD-PNC) to alleviate degradation due to the …

Two-path successive relaying (TPSR) systems have been recently proposed as powerful
candidates for improving the spectral efficiency of cooperative communications. The …

Phase noise is one of the major impairments that degrade the performance of orthogonal
frequency division multiplexing (OFDM) systems. When an OFDM system works at high …

Due to the imperfection of practical oscillators, phase noise (PHN) inevitably occurs in the
phase of desired signals, and may incur significant degradation in the performance of …
