Hi there, If anyone have codes for a repeater using kalman filter written in matlab, could you provide me? Many thanks in advance.

## Noise cancellation using IIR LMS and Unscented Kalman for speech enhancement

Hiho, I am doing research using matlab- R(2011a) for noise cancellation using IIR LMS and unscented kalman filter. But I don't know how to create the code using matlab for IIR LMS. And for UKF, i dont know what is the equation of non linear state equation representing speech. Please could some experts can (...)

## wiener filter matlab code

## Kalman filter for channel estimation

Can anyone please provide me with the matlab code for channel estimation using a kalman filter (in presence of noise)... It is urgent... Thank u...

## channel estimation with kalman filter

i want to do channel estimation using kalman filter. this is the matlab code i formulated using the equations. the noise added is gaussian. but the problem is that i am getting a constant error instead of error getting reduced with the number of iterations. can anyone please help me to find the correction needed in this... (...)

## Low Pass Filter to filter out harmonics from a signal. (MATLAB CODE)

very useful. But in a situation where you have your data already and you want to filter the noise, is the same code applicable??. because this seems to generate its own data and then apply the filter.

## speech enhancement using lms

I implemented an LMS code in matlab for removing the noise present in the speech signal and the noise is getting removed but only before and after the speech segment. ie the noise added over the speech remains the same. I used the following algorithm 1) noise estimation using VAD. I found (...)
