How can I plot Nakagami-m fading channel?

How can I plot Nakagami-m fading channel? How to do simulation like Rician and Rayleigh fading channel? Does anyone have a code?

[Muhammad Nasar ud din]

I also need the code of Nakagami fading channel Mofadal Alymani..

[sai shankar]

clc; clear all; close all;

colors=['r','g','b'] ;

m = 1;

x = [0:0.05:3];

for w = 1:3

for ii = 1:length(x)

y(ii)=((2*m^m)/(gamma(m)*w^m))*x(ii)^(2*m-1)*exp(-((m/w)*x(ii)^2));

end

plot(x,y,colors(w))

hold on

end

xlabel('Support');

ylabel('PDF');

title('probability density function')

hleg1 = legend('w=1','w=2','w=3');

set(hleg1,'Location','NorthEast')

axis([0 3 0 2]);

grid on

thanks for the script @sai shankar

I also really need the code to simulate the nakagami channel. Can anyone please help?

[Fernando Moya]

Hi Muntaseer, were you able to find the way to simulate Nakagami channel? I need the same

Hi Mofadal,

For Nakagami-m fading channel I would like you to go through the file exchange provided by the Jamal Ahmad

https://www.mathworks.com/matlabcentral/fileexchange/42322-pdf-of-nakagami-distribution

[Mofadal Alymani]

This is not an answer for my qustion. I know how to do a PDF of Nakagami distribution. I saw this link before.

I need a code or a function like "comm.RicianChannel", so I can do a sumilation of Nakagami channel.

Thanks for your comment.

Hi! Ankush Koundal,

Hope this reply finds you well. Please see the following link for the generating the different distributions i.e., Nakagami-m, Rayleigh, Rice, etc. https://www.mathworks.com/matlabcentral/fileexchange/7309-randraw

You can use the following code line to draw Nakagami distibution with shape parameter of m and n random numbers;

h=randraw('nakagami', 1, [1,n]); %m=1 case of Rayleigh

Thanks @Ali Raza

[ALPER ATES]

Could you please tell me how can i get the Rayleigh case by using Nakagami distribution following code 'h=randraw('nakagami', 1, [1,n]); %m=1 case of Rayleigh'.

I know , when m=1; case of Rayleigh but what about scale parameters n ( in other words omega) ?.

Which n value do I need to choose as the scale parameter to obtain Rayleigh case by using following nakagami -m distribution matlab code 'h=randraw('nakagami', 1, [1,n]); %m=1 case of Rayleigh',

[Adel Litim]

use this command to get help : randraw('nakagami')

you can use this function :

randraw('nakagami', [m, omega], sampleSize)
