Hi everyone, I have a gaussian noise corrupted image and I need to know how can I find the MMSE estimate of the entire noisy image in matlab? or how can I find the MMSE estimate of a gaussian noise vector/signal (because I can divide the entire image into small patch vectors)? Thanks.

I have a beamformed output, say y = weights * signal, where the signal is gaussian,i.e signal = randn( 1 , 1e5 ). Now I want to visualise the output in angular domain, i.e I want to plot the gain of the resulting signal y as a function of elevation angles. I am considering the mainlobe of 'signal' to be pointing in (0 azimuth,0elevation).
in my recent work for wsn , i faced some questions about what is the differences gaussian Source ,gaussian *Noise,and and gaussian Distribution nodes for wireless sensor network . and how i can implement that in matlab ? :shock::shock::shock:
AWGN - Add White Gausian Noise. to generate white gaussian noise u need function that generates random numbers with gaussian distribution (example randn in matlab) If your enviroment doesnt have gaussian distributed random generator you have to make one using standard random generator ( ex. rand function). So u have to: (...)
a random Rayleigh flat-fading channel object based on Jake?s model is generated in matlab with sampling period of 10 μs and the maximum Doppler shift is set to 200 Hz. The additive white gaussian noise with SNR of 23 dB is used. The required BER is set to 10−3 and the average transmit power is fixed at 0.2 W. Two independent simula
Need help with iterative wiener filter code from gaussian noise addition to performing the iterations
Hey I am using CST for 3D FDTD simulation. I can do 2D and 1D in C or matlab code but with 3D code becomes complicated hence I want to shift to CST. I understand that CST microwave studio can do the job for me. I just want 5x5x5 m 3D space and take a gaussian source somewhere within this space. I want to visualize how the E or H field is changing
I want to plot BER vs SNR, i have values for Eb/No. kindly suggest relation between BER & SNR using matlab
hi i need matlab code to use gaussian Mixture Models as classifier i have project in language identification and i see some similar projects who use gaussian Mixture Models but i don't know how to build it in matlab
hello..I have a problem. I want to know how to design a pulse shaping FIR filter in matlab when the input to this filter is gaussian pulse. Could you help me please? In my case the output of this pulse shaping filter should be 5th order derivative gaussian pulse. Thanks. waiting for the reply.

Hi, does anybody has matlab code for papr reduction of ofdm by weighting factors such as rectangular, gaussian weights. I am stuck up in my final project because of this, if somebody can help, i would be very thankful. Please it would be greatful.:-(
how to write a matlab code for generating received e in e=hG+n channel :?: zero-mean gaussian noise
I want to obtain the reflection coefficient using FFT in a transmission line, the source was excited with a gaussian pulse. Τhis is an abstract from a paper that I have as guide: "In order to obtain the reflection coefficient, the coaxial cable was excited with a gaussian pulse of the form Vs (t) = exp(-(t − 3Ts)/Ts) Ts =1/2fmax w
Hello all, I want to determine the power level (dB amp) of (supposed to be wgn) random signal using oscilloscope data. I have compiled a code to do the job but when tried to verify my code for several different signals (periodic sinus, random gaussian) generated on matlab, I have seen that the code yields different power levels for different sig
I need code for adaptive equalizer to remove intersymbol interference in the output signal. My case : the original signal is convoluted with another signal and gaussian noise is added to the result. I have to use adaptive equalizer to remove the ISI in the output signal. Can anybody send me a link from where i can download this code? thank
its your consideration, matlab doesnt know what is db and what is not db you have to treat that variable like it is in db
hi every one i need gaussian Mixture Models matlab code to use in dialect identifcation, speech recognition or speaker recognition system
Hello, Looking for how to modelize with matlab OFDM with QPSK in a gaussian channel. THANK YOU VERY MUCH
