ok, here's a script in matlab it's about the simulation of a GSM norme, you can find in the first part the emission of signals and in the second the LPC code and the calcul of pitch too
can anyone send the matlab code for predominant pitch estimation in audio signals??????
I am doing a project in speech analysis and would greatly appreciate any help on how to solve the following problem at hand: Problem a. Using linear predictive analysis, autocorrelation method, implement a matlab based vocoder for a speech signal (any recorded tape). Use a 20 msec frame step combined with a symmetrically Hamming window of 30 mse
hi ,all how to make the program for doubly selective channel estimation ,thank you
Hi all I am a new in matlab. I need to use line spectral pairs for my sensor signals. So, is there anyone who knows how to use it in matlab? Any help appreciated. Thanks beforehand!
Hi all, I'm trying to do pitch estimation using autocorrelation function. I've calculated ACF in frequency domain(fft,ifft) but the result isn't true. The input speech is voiced so the ACF should be periodic along time axis, but the result is vice versa ,i.e., it's periodic along frequncy axis!! another question: Is acf=ifft(|fft(x)|^2) same as t
Hi, If my understanding of the question is correct, all you need is estimation of pitch(fundemental frequency) at various points in time. You could just type "pitch estimation of voiced speech" in google and find loads of literature. Two simple methods are autocorrelation method and (...)
Hi everyone, I'm working on the project of Emotional Detection from Speech. we plan to achieve this by using pitch estimation, energy computation, format estimation, band energy computation, and MFCC, etc. does anyone have the source code for CCS ? or any one of the above features is ok. thanks

Hi, I have a project called "pitch detection using LPC parameters with matlab code".The input voice is lowpass filtered a cut off frequency of about 900Hz and then the sampling rate (nominally 10kHz) is reduced to 2kHz by a decimation process.The decimated output is than analyzed using the autocorrelation method with a value of p=4 for the filter
I need a matlab code of channel estimation for a zero forcing equalizer. If d(n) is channel input and h(n) is the channel then we can easily get the output y(n) form y(n)=d(n)*h(n) now if i do not know the channel h(n) where I know the input d(n) and output y(n) then I have to estimate the channel and find h(n). now =[do 0 0 ; d1

Hi... I am working with LTE-A system using matlab. need to perform channel estimation in lte A. can anybody help me out of this????????
Hi I want to estimate the parameters of the static tustin friction model, which is given by Fr = Fc*sign(v)+(Fs-Fc)*exp(-v/vs) +Fv*v where v is the joint velocity for example. I've taken experimental datas for the pairs (v, Fr) and now I want to estimate the static parameters Fc, Fs, Fs and vs. In a paper, that I've read

I am studying Spectrum estimation and the book I have doesnt provide good examples. I would appreciate if someone direct me to material where I can find good and direct-simple examples, particurlary the periodogram method, Blackman-Turkey Method, and Parametric estimation -autoregressive model, yule walker equation. It is gonna be best if t

I am currently trying to simulate Block RLS for SC- MIMO using STBC. I am attaching the paper. While Reading the paper I found the it was mentioned that in Value of δ used in Block RLS is very large. But in normal RlS the value of δ is usually very small around 0.1 or 0.01. Could any body tell me the approximate value of δ used in B
I need to create these two signals: 1. Non-stationary signal : for STFT analyzing and Wavelet analyzing. 2. Non-Gaussian signal: for Double-spectrum estimation. I've done some simulations using matlab, but with no satisfied results. Maybe it's because of the source signals.. Could you please tell me how to create the above two signals prop
Hello ppl, i m questioning myself why is this happening. ive implemented the following system using Simulink. basically i am feeding a 1kHz pure sinewave and multiplying it by a pulse having a period of 10 samples and pulse width is 1sample(10us). So effectively sine wave is being sampled at 10kHz. When i set the simulation time to 10ms and o
