Measuring of channel cofficient using “ KALMAN filter ”
In this paper, the channel is estimated by using kalman filter. The channel is time varying modeled as a low-Pass tapped delay line filter that is work as the FIR filter with time varying Coefficients. Here Kalman filter technique is used to estimate the time varying coefficient of the channel.
متن کاملParallelization of Ensemble Kalman Filter (EnKF) for Oil Reservoirs
This thesis describes the design and implementation of a parallel algorithm for data assimilation with ensemble Kalman filter (EnKF) for oil reservoir management. The implemented application works on large number of observations from time-lapse seismic, which lead to a large turnaround time for the analysis step, in addition to the time consuming simulations of the realizations. Provided that p...
متن کاملTime-Varying Frequency Fading Channel Tracking In OFDM-PLNC System, Using Kalman Filter
Physical-layer network coding (PLNC) has the ability to drastically improve the throughput of multi-source wireless communication systems. In this paper, we focus on the problem of channel tracking in a Decode-and-Forward (DF) OFDM PLNC system. We proposed a Kalman Filter-based algorithm for tracking the frequency/time fading channel in this system. Tracking of the channel is performed in the t...
متن کاملHistory matching of petroleum reservoir models by the Ensemble Kalman Filter and parameterization methods
The Ensemble Kalman Filter (EnKF) has been successfully applied in petroleum engineering during the past few years to constrain reservoir models to production or seismic data. This sequential assimilation method provides a set of updated static variables (porosity, permeability) and dynamic variables (pressure, saturation) at each assimilation time. However, several limitations can be pointed o...
متن کاملNovel channel estimation algorithm using Kalman filter for DS-CDMA Rayleigh fading channel
pendent of the bit estimation algorithm. The constant minimum variance method (CMVM) is used to suppress interference, We estimate DS-CDMA channel described by Rayleigh fading using a Kalman filter. A Kalman filter is proposed for the time varying channel estimation. The proposed scheme is constructed without hit estimation, that is, neither training sequence nor estimated bit symbol is used fo...
