Dear if you want to do Channel Estimation, than use lms, RLS or kalman filter. These are adaptive filters and can be easily implemented in matlab
Good Luck
Dear,
I want to design an MIMO channel estimation by the use of LME and RLS. Could you help me the matlab code?

you will always get error if you are directly using simulink blocks you have to write codes for the whole algorithm
For example , For lms Noise cancellation matlab codes are as follows:
close all;
clear all;clc;
t=1:0.025:5;
desired=5*sin(2*3.*t);
noise=5*sin(2*50*3.*t);
refer=5*sin(2*50*3.*t+ 3/20);
primary=desired+noise; (...)

Hi, I need to implement a equation for a dc motor in matlab. The eq is T=K*I^n . T is torque and I is current . I have a set of values as inputs for T and I, so, i need to find K and n at the output. Curve fitting has to be used for it.
I want the program code for it in matlab which could generate a curve and give K,n as the output.

I am implementing a wireless system in matlab-simulink ,
and in every wireless system there should be fading channel
after adding fading rayleigh block, the received signal is totaly changed
and the sample time decreased and I couldnt recover the original signal
I tried to add filters in the receiver but no changes happened.

Hi,
I need to do a matlab code to estimate the frequency amplitud and phase components from a given signal using the lms algorithm.
For example, if I have the signal: 4*sin (60*t +phi1) + 2*sin(120*t +phi2) the code must return indicating a 4 unit amplitud in the frequency of 60Hz and a 2 unit amplitud in the frequency of 120 Hz. And (...)

The advantage of using adaptive algorithms are based on their computational complexity, rate of convergence etc. A good reference to this is 'Adaptive Filter Theory' by Simon Haykin. Once upon a time i did do some simulations on these algorithms in matlab for purpose of comparison.
