FIR Filters for Stationary State Space Signal Models

چکیده
Abstract: A new finite impulse response (FIR) prediction is presented for a state space signal model. The linear predictor proposed in this paper uses the finite number of inputs and outputs on the recent time interval while the infinite impulse response (IIR) predictor with feedback and recursion uses all inputs and outputs from the initial time to the current time. The Yule-Walker equations for the linear forward and backward predictions are obtained from the correlation among states at each time and the orthogonality principle. How to solve these equations without an inverse of a big matrix is discussed. It is shown through simulation that the proposed FIR predictor can be as robust to modelling uncertainties as conventional robust IIR predictors. It is also shown that the good performance is achieved even in the steady state without uncertainties.

H2 / H∞ FIR Filters for Discrete-time State Space Models
In this paper a new type of filter, called the H2 / H∞ FIR filter, is proposed for discretetime state space signal models. The proposed filter requires linearity, unbiased property, FIR structure, and independence of the initial state information in addition to the performance criteria in both H2 and H∞ sense. It is shown that H2, H∞, and H2 / H∞ FIR filter design problems can be converted into...
متن کاملA Novel Interference Rejection Method for GPS Receivers
This paper proposes a new method for rejecting the Continuous Wave Interferences (CWI) in the Global Positioning System (GPS) receivers. The proposed filter is made by cascading an adaptive Finite Impulse Response (FIR) filter and a Wavelet Packet Transform (WPT) based filter. Although adaptive FIR filters are easy to implement and have a linear phase, they create self-noise in the rejection of...
متن کاملOptimal horizons for a one-parameter family of unbiased FIR filters
In this paper, we find the optimal horizons and sampling intervals, both in the sense of the minimum mean square error (MSE), for a one-parameter family of the discrete-time unbiased finite impulse response (FIR) filters. On a horizon of Nl points in the nearest past, the FIR and the model k-state are represented with the l-degree and m-degree polynomials, respectively. The noisefree state spac...
متن کاملMin-Max Design of FIR Digital Filters by Semidefinite Programming
Robustness is a fundamental issue in signal processing; unmodeled dynamics and unexpected noise in systems and signals are inevitable in designing systems and signals. Against such uncertainties, min-max optimization, or worst case optimization is a powerful tool. In this light, we propose an efficient design method of FIR (finite impulse response) digital filters for approximating and invertin...
متن کاملProperties of predictor based on relative neighborhood graph localized FIR filters
A time signal prediction algorithm based on Relative Neighborhood Graph (RNG) localized FIR filters is defined. The RNG connects two nodes, of input space dimension D, if their lune does not contain any other node:. The FIR filters associated with the nodes, are used for local approximation of the training vectors belonging to the lunes formed by the nodes. The predictor training is carried out...
