In this algo, DESA-1 is implemented and the use of NLE operator is visible. DESA-1 is taken and implemented as described by keiser .Non Linear Operators were introduced by Teager and further introduced by Maragos and Keiser.The algo presented here is simple to use ,low in complexity and can be applied to a variety of signals.

Baseline Fit each column in "x". There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput. Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated from selected points and then applied to the data.

The MUSIC algorithm, proposed by Schmidt, first estimates a basis for the noise subspace and then determines the peaks the associated angles provide the DOA estimates. The MATLAB code for the MUSIC algorithm is sampled by creating an array of steering vectors corresponding to the angles in the vector angles.

The task of this work is to extract a signal radiating from a specific direction in the presence of a jamming signal being transmitted at same frequency. There are four cases in the first case transmitter and jammer are in different directions and are at equal range from receiver but the jammer is switched off that is there is no interference signal.

A function that takes two sequences(vectors) as parameters and computes the circular convolution . x(n),h(n) are the vectors. The vectors need NOT be of equal lengths. If they are of unequal lengths, the shorter vector is appended with trailing zeros and then circular convolution is carried out.

This function begins by deducing the wavelength of the signal's primary Fourier component. It then smooths the signal using a moving-window average -- the window is roughly top hat, of size equal to the primary wavelength. For 2-D data it will perform this function on each column of data, using the primary wavelength of the central column throughout.
