Hi everyone, I have a problem and I hope to receive your help: I am applying Adaptive Prony's Method to identify spectrum of a non-stationary signal (the signal I am processing is piece-wise stationary). Adaptive Prony's Method models each of the stationary intervals as an AutoRegressive-Moving-Average process and from that, we can find the power spectrum for each stationary i

Hi there. I have a question regarding the wireless channel model to be used on an OFDM system simulation. I have investigated for a while and most of the people use an ARMA Filter to simulate the time variations of the wireless channel, but this approach is for modeling a multipath channel. The thing is that I don't know if this model includes the distortion on the receiver do to the echoes. OFDM...

## State-space formulation of lattice-ladder filter

As I understand it, an ARMA system can be realized as a lattice/ladder filter (e.g. Matlab: tf2latc). In "EFFICIENT ALGORITHM FOR ADAPTIVE NORMALISED LATTICE FILTERS" by Nguyen, 1983 (found on IEEExplore), there is a state-space formulation of a lattice filter. Does anyone know of a state-space formulation of a lattice/ladder filter? Thomas Arildsen -- Al email til afsenderadressen g?...
