Hi all......... I want to find out angle of arrival using planer antenna array for radar (Digital Monopulse) application. For concept development, first i make 2x2 planer array, and try to find out direction of arrival of sources, further i need to make null at the direction of interference. which algorithm is better for that???? or MUSIC algorithm is suitable for that???? I try to use MUSIC algorithm for DOA application, and write codes in MATLAB for 1D MUSIC. these codes gives DOA, but have some problem; (i take linear array of 10 elements, f = 1GHz and sampling frequency Fs = 5GHz) 1) the resolution is not as good as written in literature. 2) if i take no of signal > 2 then it able to find out DOA but Estimation of no. of signal is only 2 (it gives M - H (no of multiplicity of minimun eigen values) is only 1 or 2 for all the cases). I think some problem in signal(X(t)=AS + N), which i take as; Xn = Sin (wt + k d Sin(thetha))* exp (-j*(n-1)k d Sin(thetha)) Matlab codes for that is given below; for k=1:samples % no of time instants for i=1:M % no of elements for ns=1:D % no of incoming signals S1(i,k)=S1(i,k)+ sin(2*pi*f*k/Fs + 2*pi*sin(theta(ns))/dfactor)* exp(-j*(i-1)*2*pi*sin(theta(ns))/dfactor); end end end X = awgn(S1,20); % Add white Gaussian noise to signal (M x sampless) can any one give ur valuable suggations.

Hi! I am currently investigating DSP techniques for my final-year university project. I want to create a program that uses an artificial neural network in order to classify music genres. Unfortunately, I have no prior experience with DSP. I was wondering if anyone here could point me in the right direction. I am particularly interested in DSP techniques that can be used to extract features of music which are "informative" in terms of genre classification. The only thing I can think of is BPM and dominant frequency extraction. Any help, comments or links for further reading would be greatly appreciated. Thank you!

With ESPRIT you can check the Least Means Square method against the Total Least Squares method. With MUSIC you can check e.g. Classical MUSIC agains Root MUSIC (I remember having read somewhere about a Pop MUSIC variation too...) The most interesting tests are with model mis-match scenarios. Both these methods are designed with a non-damped unscaled expunential signal in mind. Try them with either a damping term or a scale term and see how well they perform. Then try and increase the number of signals. At some point, near N/2 where N is the number of elements in the array, you might notice some changes in the behaviour of the methods.

HI everyone, I am going to do a project on implementation of DOA estimation algorithm using MUSIC. I have read the literature about MUSIC and about DOA estimation. Still I am not able to conceive the idea practically. The input signal to the array of antennas (say M antennas) is X. (consider a single snap shot) which is equal to X = (a(theta) * S) + n Then we need to find the eigen value of the autocorrelation matrix of X. There will be M eigen values and M eigen vectors correspondingly. If the number of directions is D (D < M), then the eigen vectors from D+1 to M represent the noise subsspace. So the MUSIC spectrum is given by P(theta) = 1 / (summation from D+1 to M (a(theta) * eigen vectors))^2 This is what I understand from the theoretical stuff I read. Am i right? If I write a program in MATLAB using the above logic, will it be right? Where else can I find some practical examples of MATLAB implementation? Any help will be of great use to me. Thank you.

Hi everyone, I have a question relating to direction-of-arrival (DOA) estimation for MIMO systems. When using an antenna array, would it be possible to estimate the DOA of more multipath sources than the number of antennas in the array? The DOA estimation algorithms used are those based on second-order statistics: subspace-based methods like MUSIC and maximum likelihood methods like SAGE. I would think that extracting more inputs (multipath sources) than outputs (responses of indivual antennas of the array) from a system seems doubtful. However, you can tell SAGE for example to extract a number of DOAs that is greater than the number of antenna sensors. I wonder if it would be reliable to do that? Thank you very much for your replies.

There are lots of such plots in that book. Now, computing the MSE only works with simulated data. You need to know the true DoA, and then compare that to the estimated DoA. The comparision gives an error, and from there computing the MSE of different DoA estimators or SNRs is straight-forward.

Hello All, I am currently working on Range and DOA estimation of broadband near field sources.If you could suggest a method which can estimate both range and doa of nearfield sources it would be great. If you happened to have a MATLAB code which can do this, its even great. I have a working MATLAB code for doa estimation of farfield broadband sources but when I modify that code for nearfield sources by including range , it gives me wrong values of range. So could you please help me with this problem. Thank you, Satish In the near field, there is no such things as range and DOA. You have to solve the system of equations for exact position of the source.

Hi All The problem that I am facing is as below: In a DoA estimation problem, the key point is to implement the steering vector. I have implemented MUSIC algorithm for ULA and it seems to work fine i.e. the performance becomes better with increase in SNR and resolution increases with increase in elements. Basically,in the case of ULA-MUSIC, we have to search for power in each azimuth angle's direction and select the one with maximum. And same for UCA-MUSIC, but now for a given elevation angle, we have to search for all azimuth angles. Is this correct? However, the problem tha...

After finding eigenvalues of Matrix Pencil is z. Please help me calculate theta from z. Thanks all!

MUSIC was designed to be a frequency estimator, so it can be used to estimate frequencies. If you know what you are doing, you can use the frequency estimates to estimate the corresponding amplitudes; just be aware that there is lots of superstition and mythology surrounding MUSIC and some of the derived results. Whether MUSIC is 'interesting' for these types of tasks depend entirely on the context of the analysis. MUSIC has certain shortfalls, and requires certain conditions to be guarante...
