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

open access: yes, 2016
In this paper, we consider an OFDM radio link corrupted by oscillator phase noise in the receiver, namely the problem of estimating and compensating for the impairment.

Global Calibration and Error Estimation of Altimeter, Scatterometer, and Radiometer Wind Speed Using Triple Collocation

open access: yesRemote Sensing, 2020
The accuracy of wind speed measurements is important in many applications. In the present work, error standard deviations of wind speed measured by satellites and National Data Buoy Center (NDBC) buoys were estimated using triple collocation.

Errors on errors – Estimating cosmological parameter covariance [PDF]

open access: yesProceedings of the International Astronomical Union, 2014
AbstractCurrent and forthcoming cosmological data analyses share the challenge of huge datasets alongside increasingly tight requirements on the precision and accuracy of extracted cosmological parameters. The community is becoming increasingly aware that these requirements not only apply to the central values of parameters but, equally important, also

BER estimation for wireless links using BPSK/QPSK modulation [PDF]

open access: yes, 2003
This paper introduces a method that computes an estimation of the bit error rate (BER) based on the RAKE receiver soft output only. For this method no knowledge is needed about the channel characteristics nor the precise external conditions.

Homotopy Approach for Integrodifferential Equations

open access: yesMathematics, 2019
In this paper, we present the application of the homotopy analysis method for solving integrodifferential equations. In this method, a series is created, the successive elements of which are determined by calculating the appropriate integral of the ...

INS Error Estimation Based on an ANFIS and Its Application in Complex and Covert Surroundings

open access: yesISPRS International Journal of Geo-Information, 2021
Inertial navigation is a crucial part of vehicle navigation systems in complex and covert surroundings. To address the low accuracy of vehicle inertial navigation in multifaced and covert surroundings, in this study, we proposed an inertial navigation ...

Visual and Skill Effects on Soccer Passing Performance, Kinematics and Outcome Estimations

open access: yesFrontiers in Psychology, 2015
The role of visual information and action representations in executing a motor task was examined from a mental representations approach. High-skill (n = 20) and low-skill (n = 20) soccer players performed a passing task to two targets at distances of 9 ...

Signal Estimation with Additive Error Metrics in Compressed Sensing [PDF]

open access: yes, 2013
Compressed sensing typically deals with the estimation of a system input from its noise-corrupted linear measurements, where the number of measurements is smaller than the number of input components.
