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...

Hi Please see this code , I am confused how i added the two version of signal received from two Taps with one sample delay.Initially I have done IFFT of the signal with Four subcarriers.Please guide me. x=transdata1; taps=2; p1=1; p2=0.8; gain1=sqrt(p1/2)*[randn(1,length(x)) + j*randn(1,length(x))]; gain2=sqrt(p2/2)*[randn(1,length(x)) + j*randn(1,length(x))]; channel_ifft=ifft([gain1,ga...

Hello: I would like to let you know of my new book on MATLAB which was published recently: MATLAB for Beginners: A Gentle Approach by Peter I. Kattan This book is written for beginners and students who wish to learn MATLAB. One of the objectives of writing this book is to introduce MATLAB to students in high schools. The material presented is very easy and simple to understand ...

Hi, I am looking the code for an adaptive channel equalizer. I have to do system identification in which i will pass a predefined signal or a recorded .wav file and white Gaussain noise will be added to the signal and using MMSE techtnique and LMS. I want to find the inverse of the channel so that the resulting output should be the same as input. i.e H(z)=1/W(Z) ...

hi ihave defined the Rayleigh channel in this way by three taps and producing one sample delay in each tap. can any body tell me about how i can equilize the channel at receiver. Thanks. x=transdata1; taps=3; p1=1; p2=0; p3=0; gain1=sqrt(p1/2)*[randn(1,length(x)) + j*randn(1,length(x))]; gain2=sqrt(p2/2)*[randn(1,length(x)) + j*randn(1,length(x))]; gain3=sqrt(p3/2)*[randn(1,length(x)) ...

Hi everybody, Thank you for sharing valuable information in this forum Here is my problem. I am continuously collecting vibration data from a set of bearings on a spindle. I am interested in tracking certain bearing related frequencies such as outer race ball pass frequency (BFPO), etc, in order to determine the state of the bearings (healthy operation, worn out, ...) My sampling rate is s...

dear everyone, i wanna ask if someone has ever try to make program about how to make hilbert spectrum in MATLAB. im working in vibration signal processing...i still dunno what advantage or in what condition (either signal or state) hilbert spectrum is superior than FFT???? i've also try to find some info about hilbert spectrum, but no one has ever give the implementation in MATLAB ,specif...

Hi to everyone, I need to plot the PSD of a L band signal and I don't know how to define the timeline without having this error: "Maximum variable size allowed by the program is exceeded". The point is that I have problems with memory due to the high frequency I'm using. If the carrier is 1.3 GHz, the sampling frequency must be 3 or 4 times higher and matlab runs out of space and, therefore,...

Hi all, I've a problem with regards to the above subject. Currently, I'm using a VSG to transmit a PN sequence using BPSK. I am using Matlab to do data processing (BER) but there are too many errors which is wrong. Since I used a direct cable to connect the VSG to a computer which saves the data. Therefore I've decided to implement some kind of equalizer(channel estimation) in Matlab. I've r...

At the moment I am working on my thesis on "fault detection in pumps using vibratory signal analysis". This is to be done by comparing two groups of the signals, one for normal state of the machine and another attributed to its faulty conditions (in which a specific fault is artificially imposed to the system under the same working conditions as of the normal state). My problem is a high-amplitud...
