The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.The discrete input is... Platforms: Matlab

Shows graphically the various stages of discrete convolution for any two 1-D signals.This is for educational purposes really so the screens are optimized for signals of a few samples. Between two stages the figure pauses and requires the user to strike a key to continue. This should allow... Platforms: Matlab

Matlab code for the algorithm published inV. G. Reju, S. N. Koh and I. Y. Soon, Convolution Using Discrete Sine and Cosine Transforms, IEEE Signal Processing Letters, VOL. 14, NO. 7, JULY 2007, pp.445-448. Platforms: Matlab

EDFT (Extended Discrete Fourier Transform) algorithm produces N-point DFT of sequence X where N is greater than the length of input data. Unlike the Fast Fourier Transform (FFT), where unknown readings outside of X are zero-padded, the EDFT algorithm for calculation of the DFT using only... Platforms: Matlab

This function generates a Timeseries file which can be used for Moore FSM coverage analysis.The file is generated in the working directory and can be opened into the Workspace for use by MATLAB, or read directly into Simulink using the 'Import Data From File' source block.The generated Timeseries... Platforms: Matlab

Y = DCTN(X) returns the discrete cosine transform (DCT) of X.X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y.Y = DSTN(X) returns the discrete sine transform (DST) of X.X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y.X and Y can be N-dimensional.D =...

Compute the discrete Fourier transform at specified frequencies, not using fft.Why one may need this?(1) MATLAB fft function computes the amplitude of signals only (no phase).(2) Once having the recorded time-series data, one often uses fft to do the spectral analysis. However, the frequency set... Platforms: Matlab

The MDP toolbox proposes functions related to the resolution of discrete-time Markov Decision Processes: backwards induction, value iteration, policy iteration, linear programming algorithms with some variants.The functions were developped with MATLAB (note that one of the functions requires the...

Matlab implementation of the computer model of atrial fibrillation originally published by Gordon Moe and colleagues in [American Heart Journal 1964; 67(2):200-220.] To run the simulation, just type the function name (afib). It accepts no input or output arguments. Several model parameters can be... Platforms: Matlab

The Self-Tuning Controllers Simulink Library contains various discrete single input single output (SISO) controllers. All controllers contain an on-line identification of a controlled process using the second or the third order model and thus are also suitable for a control of time varying... Platforms: Matlab

This toolbox was written by Fredrik Lingvall and Bogdan Piwakowski.The DREAM Toolbox is an open source MATLAB and Octave toolbox for simulating acoustic fields radiated from common ultrasonic transducer types and arbitrarily complicated ultrasonic transducers arrays.The toolbox includes a set of...

[A,B,C,D]=era(h,n,N,Ts,def);This function returns the state-space model (A,B,C,D) in continuous or discrete time. The input parameters are the discrete-time impulse response function (IRF); the order of the system; the number of samples to assembly the Hankel matrix and the sample... Platforms: Matlab

This block for Simulink provides a chirp source for stimulating unknown system dynamics. The block has been developed specifically for the purpose of system identification, however it should be of interest to anyone looking for a robust and flexible chirp function. The chirp function is modelled... Platforms: Matlab
