Hi. i require matlab code for following

any random signal which is not modulate passing through awgn channel.

now this noisy signal equalize by lms algorithm. obtain original signal.

i did the following code;

m = 3e2;

x = randint(m,1);%%generate signal

snr = 10;

xnoisy = awgn(x,snr);%%add noise

nweights = 7;

stepsize = 0.5;

alg = lms(stepsize);%% create lms object

eqsignal = lineareq(nweights, alg);%% create equalizer object

y = equalize(eqsignal, xnoisy(1:m), x(1:m));%%equalize.

is this correct????????

please check it and please tell me how i check the output is correct or

not i.e. original signal is getting or not.

well .. your original signal is x; just check whether y = x. I wonder what makes
you think that your code is incorrect. Actually this problem is very simple and
can be easily tackled without using inbuilt matlab functions.

create a random signal x

create an awgn channel h

perform y = conv(x,h)

y is noisy signal

code up the lms equation; its fairly straight-forward, wikipedia or google for it

x_hat = lms_filter(y, taps)

check if x = x_hat
