## I need Matlab for this system dynamics

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. (...)

## AWGN generator blockin system generator

Hi all, I am looking for additive white gaussian noise generator . I found that the LogicCore is discontinued by xilinx. I would like to try using system generator , but my matlab version seems incompatible with system generator. Can anyone help me some ways , how can I add WGN to my signal and verify it whether its (...)

## Basic digital communication

From where this "white" word come in additive white gaussian noise .? ( I know that PSD of noise is flat but why white ??) Plz help

## Gaussian noise in matlab

here is some details on the gaussian noise additive white gaussian noise - Wikipedia, the free encyclopedia also there is a function in matlab called awgn you can use the help of matlab to get some details on it or

## How to add AWGN(Additive White Gaussian Noise) to a signal using C code

Dear Sir i need to know how to add AWGN(additive white gaussian noise) to a signal using C code...please provide me with some guidelines...

## Question related to SNR - the total transmit power

Hi all In multiuser OFDM, suppose the average SNR per subcarrier is 15dB. The variance of additive white gaussian noise at each receiver is assumed equal and unified (means =1). The average channel gain is from 0.1 to 1. From this, can I compute the total transmit power? Please help me Thank you

## Need help in Rayleigh fading channel

Hi I'm simulating according to the existing paper. However, I dont understand some parameters and dont know how to generate them. Could anyone please help me? "The variance fo additive white gaussian noise at each receiver is assumed equal and unified. The fading channel is three-path Rayleigh fading channel with (...)

## How to model AWGN in verilog

Hi. I need to design additive white gaussian noise in verilog..can anyone help me out? Thanks in advance. Sudhir Dakey

## Wiener filter question

Hi, everyone. When I did a question on Wiener filter, I do not know how to deal with it. The question is as follows. _____________________________ It is known that a certain object g(x,y) of size 256X256 is filtered by h(x,y) and then is corrupted by white additive gaussian noise n(x,y) to become i(x,y). We observe (...)

## Explanation of the Shannon's law equation

The Shannon-Hartley capacity theorem computes the system capacity (C) of a channel with additive white gaussian noise (AWGN). You need to realize this theorem only sets a theoretical limit on transmission rate, not error probability. It is: C = W * log2(1 + S/N) S/N is the average signal-to-noise (...)

## Matlab code to calculate curves between Ioc/Ior(dB) and frame error rate (FER)

Ioc cell interference power density Ior total trnsmitted power densityby mobile. Ioc / Ior means SIR of received signal to get it from link level simulation for additive white gaussian noise (AWGN)

## Question on the square root raised cosine filter (SRRC)

Hello tohji, Suppose that the noise at the input of the receiving SRRC filter is AWGN (additive, white and gaussian noise). The noise Power Spectral Density (PSD) at the output has a shape proportional to |H(f)|^2, this is a raised cosine shape. The autocorrelation function of the (...)

## White Gaussian Generator for XILINX

Hi max19:77, I am not familiar with Xilinx library but if you needs additive Gaussion white noise most probably you will be able to do it using simple PRBS folowed by the low-pass digital filter and finaly decimator. Regards dora
