Lower Bound Analysis For Large Errors In Nonlinear State Estimation
1988 Edition, Volume 2, January 1, 1988 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper addresses the problem of estimating a state vector from a sequence of data generated by a nonlinear process. In particular, the effects of nonlinearity on performance bounds for large estimation errors are analyzed via the marginal...

Blind estimation and mitigation of nonlinear channels
2011 Edition, September 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Nonlinear distortions in the analog frontend are becoming a growing problem. With rising requirements it becomes more expensive to provide components with sufficient linearity. Especially in the receiver, where out-of-band radiation is not an issue, relaxing the...

In-Memory Processing on the Spintronic CRAM: From Hardware Design to Application Mapping
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Computational Random Access Memory (CRAM) is a platform that makes a small modification to a standard spintronics-based memory array to organically enable logic operations within the array. CRAM provides a true in-memory computational platform that can...

Near the Cramér–Rao Bound Precoding Algorithms for OFDM Blind Channel Estimation
2012 Edition, Volume 61, February 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The authors present a blind channel estimation of cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM) systems with nonredundant precoding based on second-order statistics. The study analyzes first the mean square error for the...

Differential Evolution Algorithm Aided Turbo Channel Estimation and Multi-User Detection for G.Fast Systems in the Presence of FEXT
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The ever-increasing demand for broadband Internet access has motivated the further development of the digital subscriber line to the G.fast standard in order to expand its operational band from 106MHz to 212 MHz. Conventional farend crosstalk (FEXT) based...

Channel, Phase Noise, and Frequency Offset in OFDM Systems: Joint Estimation, Data Detection, and Hybrid Cramér-Rao Lower Bound
2014 Edition, Volume 62, September 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Oscillator phase noise (PHN) and carrier frequency offset (CFO) can adversely impact the performance of orthogonal frequency division multiplexing (OFDM) systems, since they can result in inter carrier interference and rotation of the signal constellation. In this paper, we...

In-Memory Processing on the Spintronic CRAM: From Hardware Design to Application Mapping
2019 Edition, Volume 68, August 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Computational Random Access Memory (CRAM) is a platform that makes a small modification to a standard spintronics-based memory array to organically enable logic operations within the array. CRAM provides a true in-memory computational platform that can...

Dynamic Cramer-Rao bound for target tracking in clutter
2005 Edition, Volume 41, October 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recently, there have been several new results for an old topic, the Cramer-Rao lower bound (CRLB). Specifically, it has been shown that for a wide class of parameter estimation problems (e.g. for objects with deterministic dynamics)...

Single Space Based Sensor Bias Estimation using a Single Target of Opportunity
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Sensor registration refers to the estimation/compensation of systematic (bias) errors, in contrast to the random errors from sensor noise. Various methods have been proposed for bias estimation of multiple optical sensors using common targets of...

Nonlinear multiuser parameter estimation and tracking in CDMA systems
2000 Edition, Volume 48, December 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a joint channel coefficient and time-delay tracking technique for code-division multiple-access (CDMA) systems. Due to the highly nonlinear nature of time delay estimation, an iterative nonlinear filtering algorithm, called the...
