## Channel Capacity Matlab

Hello everyone, I have this little task to do and I need your help. I have to plot the capacity of an AWGN channel and a fading channel in function of the SNR. The code must be written in matlab. Can someone please give me some hints of how to get started, what the input of the channel should be, etc.. (...)

## channel model in matlab by using rayleigh fading model

i just need the matlab code for the estimation of channel in matlab code. ---------- Post added at 19:56 ---------- Previous post was at 19:36 ---------- i am doing my project on capacity analysis of under water acoustic mimo communications in that i have to do a channel model in rayleigh fading model. i nee

## matlab code for the capacity of the MIMO channel

can anyone help me with a matlab code to implement the capacity of the mimo channel

## Freq. Selective Multipath Ch. Cap. Code but need some help

Hi all! I added a matlab code about frequency selective multipath channel capacity calculation for 1x1 channel but i have to improve it. Can anyone help me to write the code for 1x2 , 1x3 , 2x2 and 3x3. I have to make some changes in loops to succed it but i couldn't. If anyone has any idea about this code and/or (...)

## the relationship between numbers of users and BER in CDMA

Hi，friends， I want to analyze the relationship between numbers of users and the BER, as well as channel capacity in a asynchronous CDMA system. Assume that there is not any special multi-users detection algorithm. How can the formula be derived and how can I do the related simulation in matlab? Please give your advice. (...)

## Implication of channel capacity as a function of Eb/No

I think the SNR in channel capacity equation is Es/No instead of Eb/No. C=W*log(1+Es/No) ?

## HELP Needed for Matlab simulation for rate 1/3 encoder decod

Hi, I am working on this project where in I have to simulate (matlab, C) a rate 1/3 encoder decoder ( soft or hard) to get minimized gap to capacity over a AWGN channel compared to un coded BPSK. Also I have been given a sample skeleton in which I just need to modify encoder and decoder part else I can write a new program is I want. Can (...)

## capacity problem - how to simulate this integral via matlab

hi all this equation represents the capacity of flat fading channel C=int.( from 0 to inf) of B*log (of base 2)(1+gama)*p(gama)d(gama) d(gama) thee integration over gama B=bandwidth of channel gama=SNR p(gama) is exp. function which represent probability distribution of the received SNR the question is how to simulate this (...)

## for good programmer- how to make integartion via matlab

hi in channel flat not AWGN the capacity form is integartion as all know i need this integration , so how to make integartion via matlab so the output is vector not number althogh the integation is limited (i.e from number to inf) in other word how to plot the capacity via matlab

## Capacity of a Rayleigh fading channel

Can some one help me with matlab code for :capacity of a Rayleigh fading channel For mula:(file) Thank you!

## MIMO Matlab capacity plot

Hi to all!I need to plot capacity-VS-SNR for some MIMO configuration for my thesis. The formula I'm tryin to use is C=\log_2 \left Where M, N are the numbers of RX and TX antenna. H is the channel matrix and to generate it: H=randn(M,N)+i*randn(M,N) Can anyone h

## Help me simulate MAC Channel with Rayleigh fading in Matlab

hi guys, I want to simulate the MAC channel with rayleigh fading using successive interference cancellation showing that the pantagon region is achievable. Pantagon region is the the capacity region achievable by two user sending information at the same time to common destiation. I want to use matlab for this. Thanx

## channel modeling for mimo sytems..please help urgently

i want to produce a GUI in matlab that 1.shows recieved signal envelope for mimo channel in flat fadig and frequency selective channel(signal strength against time) 2.shows improvement in capacity as number of transmit and recieve antennas changese.g 1*1,2*3,etc 3.shows inmprovement in fade margin as number of transmit (...)

## Monte Carlo Simulation for this problem (MATLAB):

Hi, You need to simulate the capacity formula for MIMO which u already mentioned. But then you have to run the simulations for long time, for Ricean fading use channel mean non-zero and for Rayleigh fading use channel mean zero. I am attaching a figure with this post, which is Sum capacity vs Number of users in the (...)

## Plz Plz help me in wireless communication

Hi, I get very challenging question that I have to plot using matlab the single-user channel capacity with rayleigh fading how can I do this for range between 0-30 dB average SNR.The plot is found in Wireless Communications P.114,115.I did all my best ,but there was not any matchs between my results and the book's. How can I chose the (...)

## Channel Capacity plotting

Hi,how can I plot the channel capacity using matlab for average SNR from 0 dB to 30 dB if the CSI is log-Normal distribution ,What is the Average SNR and what is the difference between Average SNRand SNR,how can I calculate the best standard deviation that gives me high capacity .Only given to me the previous range (They (...)
