Information on the future state of time varying frequency selective channels can significantly enhance the effectiveness of feedback in adaptive and limited feedback MIMOOFDM systems. This paper investigates the parametric extrapolation of wideband MIMO channels using variations of the double directional MIMO model. We propose three predictors which estimate parameters of the channel using 4D, ...

The Air Force Office of Scientific Research supported the research on MIMO radar carried out at the New Jersey Institute of Technology during the period from April 2009 to November 2011 under the agreement number FA9550-09-1-0303. The purpose of this report is to summarize the proceedings and findings of the studies supported by this agreement. The report addresses two broad topics: (i) perform...

Non-line-of-sight (NLOS) propagation, which widely exists in wireless systems, will degrade the performance of wireless positioning system if it is not taken into consideration in the localization algorithm design. Different from existing approaches which treat NLOS measurements as outliers and only work when there is a large number of measurements, in this paper, we propose to use Maximum Like...

The aim of this correspondence is to report in a closed-form expression a lower bound on the performance of sampling clock frequency offset (SFO) estimators for both single carrier and multi-carrier linearly modulated signals. This benchmark is expressed in terms of the so-called modified CramerRao bound (MCRB), which is shown to coincide asymptotically asymptotically (large sample) with the Cr...

This contribution considers the joint estimation of the carrier phase and the frequency offset from a noisy linearly modulated burst signal containing random data symbols (DS) as well as known pilot symbols (PS). The corresponding Cramer-Rao lower bound (CRB) is derived. This bound indicates that it is potentially more accurate to estimate carrier phase and frequency from such a ‘hybrid’ burst ...
