Electrohydraulic servo systems provide one of the best controllers from the point of view of precision and speed of response. They are used to control almost all hydraulic and mechanical parameters, such as the pressure, pressure difference, angular speed, displacement, angular displacement, strain, force, and others.

The correlation function calculated from one realization of an ensemble is inherently flawed since the expectation operation does not come into play. Hence it is important to have an idea of the variance in the correlation function..

This function estimates 2D-2D projective homography between two images using DLT, RANSAC and Lev-Mar optimisation. The format for calling upon the function is as follows: [h wim] = homography(im1, im2); where im1 -> 1st Image im2 -> 2nd Image h -> Returned homography matrix wim -> Warped version of im1 w.

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that: - The frequencies of the harmonic components are unevenly spaced - The time vector is unevenly spaced In such cases we could be in the need of coding the summation directly in Matlab, that is quite slow in performing this tasks.

This function deconvolves one extremely large vector out of another extremely large vector very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type "help fdeconv".

The sound denoising algorithm is based on the popular spectral subtraction technique. Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT.

These programmes are not heavily commented but infact are very simple and intutive to understand the Frequency hopping and related tasks. I have made two files for frequency hopping, one of them is not showing 6 proper impulsive peaks but other programme is infact showing them, In DSSS i have generated 20 bits and each bit is 6 units long and then it is XORed with another pseudorandom data bits and then it is BPSK modulated and hence two peaks in its FFT are displayed.

[psi gopt] = dfdesign_w_lmi(phi, w, d, n); DFDESIGN_W_LMI computes the H-infinity optimal inverse FIR filter of phi(z). The resulting filter minimizes the H-infinity norm of the error system E_w(z) = [z^(-d) - psi(z)phi(z)]w(z). The LMI method based on KYP lemma is used in this function.

A stack-based sequential depth-first decoder that returns Maximum-Likelihood solutions to M-QAM modulated MIMO system-type problems, i.e., a lattice decoder with optional justified rectangular boundary control. In such problems, the depth of the search tree is known and the number of children per node is also fixed.
