The motive for posing this questions arises from a difference of analysis between a colleague and myself. Our general environment is in the construction of an analog front end which takes in signals to an instrumentation amp in the low microvolt range. followed by a gain stage, which then feeds a 24 bit delta sigma converter. My understanding
Hi everyone, I'm trying to simulate an OFDM following a few steps, and I'm stuck at the first: The first step: You have a channel with independent zero mean complex gaussian taps along with exponentially decaying power profile E{|hk|2|}=e-k/3 with k ∈ First of all, does this nota
When you write h=X+jY then X and Y are orthogonal. And since they are gaussian random variables then they're independent.
Please post a code so that we can generate gaussian noise using vhdl that is synthesizable. The non synthesisable code is givenbelow. You may also mention the portions that we can edit in this program to make it synthesisable. That's like asking to do the homework. I am providing an alternative! Can't you not translate the co
We need a noisy sine wave signal. We have generated the sine wave(using VHDL), but we cant figure out how to add noise to it. We are including the code for sine wave generation. Kindly mention how to add gaussian/any other noise to it. library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.NUMERIC_STD.ALL; --try to use this library as much
Hi, What is the difference between a gaussian pulse and gaussian mono-cycle pulse? Thanks
Hello, please can anyone provide me with the expression of the gaussian pulse in 3D Thanks for all!
Hi, Is there a block in virtuoso where I can input the time domain impulse to get the required characteristics? The reason why I am asking is because I am trying to model an optical channel which has a gaussian impulse response and modeling the transfer function using svcvs is a bit tedious. I have the time domain impulse response and it would b
GPRS (General Packet Radio Service) uses GMSK (gaussian Minimum Shift Keying). This is (can be seen as) a variant of OQPSK (Offset QPSK) coherently detected. Z
Hi I'm experimenting with power line communication by connecting 2 modems (Texas Instuments PLC developer's kits) through 100m of RG58 coaxial cable as a model power line and injecting white gaussian noise with a signal generator. The modems exchange modulated packets of data shown in fig 1. I was hoping to see the response of the Bit error r

Log-normal or other non-gaussian / non-uniform stats will have means that are not centered in the span. Nonlinear circuit elements can make response of uniform stats, one-end-weighted. I have not seen the form of stats posted by erikl but the std= appears to make an unequally-weighted distribution?
Hello everybody, i'm new in the forum. I have a fundamental doubt and I can not get over it. If I measure a sine on a spectrum analyzer, how I can measure it's bandwidth? Let's suppose a have a gaussian shape with a certain 3db bandwidth; my problem is that if I change the frequency window, resolution and sampling time/points, my result changes
Hello everyone :) I'm working on a project for fingerprints recognition and I'm actually trying to code the Gabor filter but I'm encountering many problems though I'm applying the exact formula of the filter!! I don't know what's the problem. I start by normalizing the image (mean = 0 and variance = 1) Then I calculate the local orientation
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.

Hi all, I just started some weeks ago working with CST and have a question concerning F-Parameters. I want to calculate losses which occur if you want to couple light from a laser into a waveguide. For this i used a gaussian excitation (Home->Solver->Sources->gaussian Excitation) as source and placed a waveguide above it. Afterwards I placed
Hi, The parameter "Frequency pulse shape" in "CPM Modulator Baseband" block in Simulink can be chosen as gaussian: this the so called GMSK modulation? Senmeis
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).
Hi all, please can any one help me to find the problem with this code i want to restore an image with it but the result is a black image Img = imread('C:\images\lena.jpg'); %Img= rgb2gray(Img); Img=im2double(Img); V =0.001; clc; x_N=V ; x_R=V *2; NImg=imnoise(Img,'gaussian'); % it was NImg=imnoise(Img,'gaussian',Var); sub
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:
